Psychiatric symptoms in a patient with Churg-Strauss syndrome

We report a case of Churg-Strauss syndrome (CSS) in a patient with multiple cerebral infarctions and psychotic symptoms. A 67-year-old man presented a high-grade fever and delirium. He was clinically diagnosed with Churg-Strauss syndrome on the basis of the presence of asthma, neuropathy, blood eosinophilia, and increased myeloperoxidase-specific anti-neutrophil cytoplasmic antibody (MPO-ANCA) activities. Though multiple cerebral infarctions are irreversible, this patient's psychiatric symptoms improved with steroid treatment. Psychiatric symptoms associated with CSS are very rare.

Headache, migraine, and structural brain lesions and function: population based Epidemiology of Vascular Ageing-MRI study

OBJECTIVE

To evaluate the association of overall and specific headaches with volume of white matter hyperintensities, brain infarcts, and cognition.

DESIGN

Population based, cross sectional study.

SETTING

Epidemiology of Vascular Ageing study, Nantes, France.

PARTICIPANTS

780 participants (mean age 69, 58.5% women) with detailed headache assessment.

MAIN OUTCOME MEASURES

Brain scans were evaluated for volume of white matter hyperintensities (by fully automated imaging processing) and for classification of infarcts (by visual reading with a standardised assessment grid). Cognitive function was assessed by a battery of tests including the mini-mental state examination.

RESULTS

163 (20.9%) participants reported a history of severe headache and 116 had migraine, of whom 17 (14.7%) reported aura symptoms. An association was found between any history of severe headache and increasing volume of white matter hyperintensities. The adjusted odds ratio of being in the highest third for total volume of white matter hyperintensities was 2.0 (95% confidence interval 1.3 to 3.1, P for trend 0.002) for participants with any history of severe headache when compared with participants without severe headache being in the lowest third. The association pattern was similar for all headache types. Migraine with aura was the only headache type strongly associated with volume of deep white matter hyperintensities (highest third odds ratio 12.4, 1.6 to 99.4, P for trend 0.005) and with brain infarcts (3.4, 1.2 to 9.3). The location of infarcts was predominantly outside the cerebellum and brain stem. Evidence was lacking for cognitive impairment for any headache type with or without brain lesions.

CONCLUSIONS

In this population based study, any history of severe headache was associated with an increased volume of white matter hyperintensities. Migraine with aura was the only headache type associated with brain infarcts. Evidence that headache of any type by itself or in combination with brain lesions was associated with cognitive impairment was lacking.

Lesion size-dependent synaptic and astrocytic responses in cortex contralateral to infarcts in middle-aged rats

In young adult rats, unilateral lesions of the sensorimotor cortex lead to neuronal structural plasticity and synaptogenesis in the contralateral motor cortex, which is connected to the lesion site by transcallosal fibers. The contralesional neural plasticity varies with lesion size and results from the convergence of denervation-induced reactive plasticity and behavioral asymmetries. It was unknown whether similar effects occur in older animals. Furthermore, the coordination of synaptic responses with that of perisynaptic astrocytes had not been investigated. In this study, middle-aged rats (14-16 months old) were given sham-operations or unilateral ischemic lesions of the sensorimotor cortex. Fifty days later, numerical densities of neurons and synapses and morphological characteristics of astrocytic processes in layer V of the contralesional motor cortex were measured using stereological light and electron microscopy methods. Lesions resulted in behavioral asymmetries, but no significant synapse addition in the contralesional motor cortex. Synapse number per neuron was negatively correlated with lesion size and reduced opposite larger lesions compared with smaller ones. Astrocytic changes were also lesion size-dependent. Astrocytic hypertrophy was observed only after smaller lesions and was associated with greater coverage and greater numbers of synapses. These findings are consistent with those in younger rats indicating an inverse relationship between lesion size and adaptive neuronal restructuring in denervated cortex. However, they indicate that the synaptogenic reaction to this lesion is relatively limited in older animals. Finally, the results indicate that structural plasticity of perisynaptic astrocytes parallels, and could play a role in shaping, synaptic responses to postischemic denervation.

Neuropsychology of acute stroke

Neuropsychology includes both the psychiatric manifestations of neurological illness (primary brain-based disorders) and neurobiology of "idiopathic" psychiatric disorders. Neurological primary brain disorders provoke broad spectrum of brain pathophysiology that cause deficit sin human behaviour, and the magnitude of neurobehavioral-related problems is a world wide health concern. Speech disorders of aphasic type, unilateral neglect, anosognosia (deficit disorders), delirium and mood disorders (productive disorders) in urgent neurology, first of all in acute phase of stroke are more frequent disorders then it verified in routine exam, not only in the developed and large neurological departments. Aphasia is common consequence of left hemispheric lesion and most common neuropsychological consequence of stroke, with prevalence of one third of all stroke patients in acute phase although exist reports on greater frequency. Unilateral neglect is a disorder that mostly effects the patient after the lesion of the right hemisphere, mostly caused by a cerebrovascular insult (infarct or haemorrhage affecting a large area - up to two thirds of the right hemisphere), and in general the left-side neglect is the most widespread neuropsychological deficit after the lesion of the right cerebral hemisphere. Reports on the incidence of visual neglect vary and they range from 13 to 85%. Anosognosia is on the second place as neuropsychological syndrome of stroke in right hemisphere, characterized by the denial of the motor, visual or cognitive deficit. This syndrome, defined as denial of hemiparesis or hemianopsia, is a common disorder verified in 17-28% of all patents with acute brain stoke. There are different reports on frequency of delirium in acute stroke, from 24 to 48%, and it is more frequent in hemorrhagic then ischemic stoke. Post stroke depression (PSD) is one of the more frequent consequences on the stroke, and the prevalence of PSD has ranged from 5 to 63% of patients in several cross-sectional studies, peaking three to six months after a stroke.

Differences in quality of life after stroke and myocardial infarction

INTRODUCTION

There is obvious decline in quality of life after MI and stroke. The main factors that reduce quality of life in these patients were the inability of returning to normal activities, pain and the development of depression / anxiety. We wanted to know what has the biggest influence on recovery and differences in quality of life in patients after stroke and heart attack.

SUBJECTS AND METHODS

Cross-sectional study was conducted using HADS and WHOQOL-Bref questionnaire. Criteria for exclusion were diabetes, previous depression, cancer or other co morbidities that influenced the quality of life. It has been surveyed total of 396 patients, of whom 378 patients satisfied the criteria of inclusion in the study. Based on the personal data of patients, they were divided according to gender, age, educational level, and social support expressed by number of members with whom patient lives.

RESULTS

In all the observed parameters of the SU group had better results than the stroke group. The recovery after a stroke affected age, length of education and depression. Age, gender and length of education influence on a heart attack recovery. Disease duration did not affect the quality of life in either group. Significantly more patients after a stroke had depression compared to MI (p<0.001). Anxiety was not found significant in differences between groups (p=0.051). Metabolic syndrome was more frequent in the stroke group, but the difference between groups was not significant (stroke/MI) (p=0.098). In the group of stroke patients who had MS patients more often had depression (p=0.003) for different of respondents from the group with MI.

CONCLUSION

Quality of life was significantly worse in patients after stroke compared to those with MI. The recovery from stroke was most significantly impacted by depression and age and level of education, while the recovery from heart attack was at most affected by gender, age and level of education.

Clinical studies on event-related potentials (ERPs) N400 and the related factors in patients with poststroke depression (PSD)

OBJECTIVE

To evaluate event-related potentials (ERPs), N400, and the related factors in patients with poststroke depression (PSD).

METHODS

Eighty-five stroke patients with depression, conforming to the diagnoses standard of Chinese Classification of Mental Diseases (3rd edition) (CCMD-3), were treated with fluoxetine hydrochloride for 3 months and another 85 stroke patients without depression were selected as the control group. The traits about N400 and blood platelet 5-HT concentrations of all patients were measured.

RESULTS

There were significant differences between the incubation periods and average amplitudes of N400 in patients with PSD and those in patients without PSD (p < 0.01), while the blood platelet 5-HT concentrations of PSD patients were much lower than those of the patients without PSD (p < 0.01). For PSD patients, the N400 incubation periods were significantly shortened, averaged amplitudes were significantly increased (p < 0.01), and the blood platelet 5-HT concentrations were significantly raised after 3 months' treatment.

CONCLUSIONS

For ERPs N400 in PSD patients, the incubation period is significantly prolonged and the average amplitude is reduced. Blood platelet 5-HT concentration may influence ERPs N400 in PSD patients.

SIGNIFICANCE

N400 detections are helpful to the early diagnostic of PSD, and provide objective electrophysiology indexes for follow-up visits.

Post-stroke depression: can we predict its development from the acute stroke phase?

OBJECTIVES

To identify possible predictive factors for post-stroke depression (PSD) in the acute phase of stroke.

METHODS

The study design was prospective, observational cohort study of patients with acute cerebral infarction (CI). Neurological and neuropsychological evaluations were conducted within the first 10 days from the onset of stroke and repeated at the 3-month follow-up. DSM-IV criteria were used to define PSD.

RESULTS

From a total of 85 patients with CI, 59 patients completed the 3-month follow-up and 17 of them (28.8 %) fulfilled PSD criteria at the 3-month follow-up. Melancholy index of the Hamilton Depression Rankin Scale (HDRS) was associated with a risk three times greater than that of PSD at the 3-month follow-up in the univariate analysis (OR 3.07; 95% CI 1.53-6.16; P = 0.002) with no significant influence of stroke severity or the location of brain infarction (right or left side). The receiver operating characteristic curves pointed to a melancholy index > or =1.5 as the optimal cut-off level associated with the development of PSD at the 3-month follow-up.

CONCLUSIONS

Melancholy index of the HDRS > or =1.5 could be a useful clinical tool to detect patients with acute stroke at high risk of developing PSD.

Mental imagery for relearning of people after brain injury

OBJECTIVE

This paper reported on the application of mental imagery to the relearning of daily task performance in people with brain injury.

METHOD

The changes in two subjects who had suffered from cerebral infarction shown throughout a 3-week mental imagery programme were described. The subjects' improvement in task performance and other clinical outcomes illustrated the programme's therapeutic effects on skill relearning, maintenance and generalization.

RESULTS

After completing the programme, the subjects showed improvements in performance at both the trained and untrained tasks. Feedback from the patients also suggested its ability to enhance their day-to-day functioning. Clinical assessment results indicated that the subjects experienced an increase in the attention and sequential processing functions but not in the motor and other cognitive functions.

CONCLUSION

Mental imagery appears to be effective at enhancing the task relearning of subjects after brain injury. The skills acquired under this treatment regime can be retained and then generalized to other tasks. Its therapeutic effect is probably mediated by the improved attention and planning and execution functions associated with the rehearsal. Further research should conduct clinical controlled trials to gather evidence on its efficacy at promoting functional regain in people suffering from neurological disorders.

High serum levels of leptin are associated with post-stroke depression

BACKGROUND

Depression is a frequent mood disorder that affects around 33% of stroke patients and has been associated with both poorer outcome and increased mortality. Our aim was to test the possible association between inflammatory and neurotrophic molecular markers and the development of post-stroke depression.

METHOD

We studied 134 patients with a first episode of ischemic stroke without previous history of depression or speech disorders. We screened for the existence of major depression symptoms in accordance with DSM-IV criteria and a Yesavage Geriatric Depression Scale (GDS) score >11 at discharge and 1 month after stroke. At these times, serum levels of molecular markers of inflammation [interleukin (IL)-1beta, IL-6, intracellular adhesion molecule 1 (ICAM-1), tumor necrosis factor (TNF)-alpha, leptin and high-sensitivity C-reactive protein (hs-CRP)] and neurotrophic factors [brain-derived neurotrophic factor (BDNF)] were measured by enzyme-linked immunosorbent assay (ELISA).

RESULTS

Twenty-five patients (18.7%) were diagnosed as having major depression at discharge. Out of 104 patients who completed the follow-up period, 23 were depressed at 1 month (22.1%). Patients with major depression showed higher serum leptin levels at discharge [43.4 (23.4-60.2) v. 6.4 (3.7-16.8) ng/ml, p<0.001] and at 1 month after stroke [46.2 (34.0-117.7) v. 6.4 (3.4-12.2) ng/ml, p<0.001). Serum levels of leptin >20.7 ng/ml were independently associated with post-stroke depression [odds ratio (OR) 16.4, 95% confidence interval (CI) 5.2-51.5, p<0.0001]. Leptin levels were even higher in the eight patients who developed depression after discharge [114.6 (87.6-120.2) v. 7.2 (3.6-13.6) ng/ml, p<0.0001].

CONCLUSIONS

Serum leptin levels at discharge are found to be associated with post-stroke depression and may predict its development during the next month.

[Case of callosal disconnection syndrome with a chief complaint of right-hand disability, despite presence of left-hand diagonistic dyspraxia]

e report the case of 48-year-old right-handed male patient with an infarction affecting most part of the body and the splenium of the left half of the corpus callosum. Neuropsychological examination revealed typical signs of callosal disconnection including left-sided apraxia, diagonistic dyspraxia, left-sided agraphia, left-hand tactile anomia, left hemialexia, and right-sided constructional disability. Moreover, he complained of impairment in activities involving the right hand disability and agraphia. He could not stop behaving with his right hand when he had a vague idea. For example, he involuntarily picked up a tea bottle with his right hand when he had a desire to drink, although the action was not appropriate to that occasion. The imitation and utilization behavior did not imply this case, because his right hand behaviors were not exaggerated in response to external stimuli, such as the gestures of the examiner or the subjects in front of the patient. Unexpectedly, he complained about impairment of the activity of his right hand and was unaware of left hand apraxia or diagonistic dyspraxia; this trend continued for 6 months, at the time of this writing. We argue that the patient may have been subconsciouly aware of the symptoms of his left hand but had not verbalized them.

[A case report of a HIV-infected patient, who was denied to return home because of his psychological complications along with hepatocellular carcinoma]

Although a social support system has been developed in recent times, some of the difficult cases which complicate serious diseases due mainly to lack of family care power, have been reported. We experienced one HIV-infected patient who suffered from hepatic carcinoma and had been taken care of at home, but he was denied to return home after hospitalization. It has been reported that the management of homecare station has become worsened and the number of stations has been decreasing in various locations. If the patients were selected by homecare stations in which the management was going from bad to worse, it would be difficult to maintain a nationwide quality of homecare system. By presenting such an extreme case in the homecare services, we propose a homecare scoring system, in consideration of homecare service limitations, which will be helpful assessing a difficult case of a patient taken care of at home.

Poststroke depression in patients with small subcortical infarcts

OBJECTIVES

Small subcortical infarcts (SSIs) can result from small vessel disease (SVD) and intracranial and extracranial large artery disease (LAD). No study has explored poststroke depression (PSD) in different etiological types of SSIs.

METHODS

Patients with SSIs resulting from LAD and SVD were included in the study. Poststroke depression was evaluated with the 15-item version of the geriatric depression scale (GDS) 3 months after stroke.

RESULTS

Of the 127 patients with SSIs, 44 had LAD and 83 had SVD. The LAD group had a significantly higher mean GDS score and higher frequency of PSD (p<0.05). The etiological type LAD was a significant independent risk factor for PSD.

CONCLUSION

PSD is more common in patients with SSIs resulting from LAD. This suggests that cerebral blood perfusion may play an important role in the development of PSD.

[A survey on cerebral infarction/transient ischemic attack inpatients compliance with secondary stroke prevention and follow-up 90 days]

OBJECTIVE

Poor compliance with evidence-based-medicine guidelines could significantly influence the effect of stroke prevention strategies. The objectives of this survey are to investigate the current status in Beijing of cerebral infarction/TIA (transient ischemic attack) inpatients' adherence to the evidence-based-medicine secondary prevention and behavior modifications both at the discharge and at 90-day follow up.

METHODS

The survey included cerebral infarction/TIA patients successively admitted from 1, Oct 2006 to 1, May 2007, used ACEI/ARB, Statin, anti-platelet agents therapy, accepted carotid endarterctomy or angioplasty or stent, and modified behaviors to stop smoking and control weight. Data of patients during hospitalization were obtained from the medical documents in the inpatient department of 7 centers. The detailed information included the medicine therapy, lifestyle modifications, patients' social demographic background (age, sex, education and way of payment), major risk factors for stroke, and ischemic event subtypes (TIA or cerebral infarction). Above information of part of patients were collected through telephone interview at 90-day follow-up if the patients were not able to visit the clinic.

RESULTS

708 cerebral infarction/TIA inpatients who didn't have contraindications were included. Among them, the patents who haven't used anti-platelet agents, nor taken statin, nor accepted ACEI/ARB were about 0.4%, 41.8% and 63.6% respectively. Neither 27% of the patients have accepted the instructions on stop smoking. While about 588 patients suitable to drug therapy were followed up at 90 days, but the percentage of these patients who haven't compliance on anti-platelet agents, statin, ACEI/ARB was 26.9%, 52.6% and 59.4% respectively. Only 66.9% of the smoking patients have received the doctor instructions on smoking cessation.

CONCLUSION

Stroke recurrence rate in China is higher than that of average figures in western countries. One of the key reasons of high recurrence of stroke in China is the poor adherence to stroke secondary prevention guidelines. Thus, investigate current status of secondary prevention among hospitals in capital of China and promote strategies to enhance the adherence to the guidelines and fill the gap between the clinical practice and evidence-based medicine in China, which is able to lower the stroke recurrence and save lives are urgently needed. Physician should take great care of the patient's compliances on the evidenced-based-medicine secondary prevents and behavior modifications, and take effective measures to improve the compliances.

[Sensory syndrome and aphasia after left insular infarct]

INTRODUCTION

Sensorial impairment without hemiplegia is usually caused by a thalamic lesion.

CASE REPORT

A 28-year-old woman presented with hemianesthesia associated with aphasia following a left insular lesion, subsequent to subarachnoid hemorrhage. Brain MRI Flair sequence revealed a high intensity signal in the left insular and frontal subcortical regions. Insular infarct was diagnosed, associated with hemorrhagic sequelae.

DISCUSSION/CONCLUSION

Study of the normal and pathologic insular cortex suggest several implications of the region in somatosensory and language functions. However, the insular cortex has been mainly associated with central pain. Lasting objective hypoesthesia has been very rarely documented. The left insular cortex has also been implicated in speech apraxia but our patient presented with fluent aphasia mostly affecting the rhythm of speech, as it has been observed in thalamic aphasia.

Voxelwise Bayesian lesion-deficit analysis

Relating cognitive deficits to the presence of lesions has been an important means of delineating structure-function associations in the human brain. We propose a voxel-based Bayesian method for lesion-deficit analysis, which identifies complex linear or nonlinear associations among brain-lesion locations, and neurological status. We validated this method using a simulated data set, and we applied this algorithm to data obtained from an acute-stroke study to identify associations among voxels with infarct or hypoperfusion, and impaired word reading. We found that a distributed region involving Brodmann areas (BA) 22, 37, 39, and 40 was implicated in word reading.

Sitting balance as an early predictor of functional improvement in association with depressive symptoms in stroke patients

The aim of the present study was to assess the relationship between sitting balance at an early stage and activities of daily living (ADL) function in 452 stroke patients. The effect of sitting balance on the two core elements of depression (apathy and depressive mood) was also examined. The ability to maintain a sitting position for 10 min (10-min sitting balance) was assessed, along with ADL using the Functional Independence Measurement, and psychological status using the Zung Self-rating Depression Scale (depressive mood), Apathy Scale (apathy) and Neuropsychiatric Inventory. Proportional-hazards analysis was used to determine the independent effect of post-stroke depression on functional outcome. Comparisons between sitting balance and psychological status were performed using logistic multiple regression analysis. Cox multiple regression analysis showed that significant differences were obtained for the sitting balance (P < 0.0002) and Mini-Mental State Examination scores (P < 0.02) in all six ADL subscales, and for age in four of the six ADL subscales (Dressing-Upper Body and Dressing-Lower Body, Toileting, Walking). Kaplan-Meier survival curves for reaching independence in ADL subscales showed highly significantly differences in achievement rate and time to reach goal for each subgroup on 10-min sitting balance (with or without assistance) and on age (young, <65; elderly, >/=65 years). Ten-minute sitting balance correlated with depressive mood and apathy. A rapid and simple screening method, 10-min sitting balance was related to scores for two core depressive symptoms, lowered mood and apathy, and was predictive of post-stroke ADL outcomes in the rehabilitation unit along with age.

Early cognitive outcome after neonatal stroke

The purpose of this study was to assess the cognitive development of 27 children with nonhemorrhagic neonatal stroke (occurring within the first 28 days of life). The cognitive evaluation consisted of the Bayley Scales of Infant Development, administered at 12 and/or 24 months poststroke. Compared with the normative sample, children with neonatal stroke obtained significantly lower scores on the Bayley Psychomotor Development Index at 12 months poststroke and on the Bayley Mental and Psychomotor Development Indices at 24 months poststroke. Outcome did not differ based on stroke type or laterality of infarct. However, there was a trend toward higher scores on the Bayley Psychomotor Development Index at 24 months in the left hemisphere group compared to the right hemisphere group. Overall, children with neonatal stroke evidenced significant impairment within the first 2 years poststroke. Further research is required to confirm whether cognitive impairments in these children resolve, remain in the low-average range, or increase with development as more complex skills are learned.

White matter changes and late-life depressive symptoms: longitudinal study

BACKGROUND

Evidence from cross-sectional studies suggests a link between cerebral age-related white matter changes and depressive symptoms in older people, although the temporal association remains unclear.

AIMS

To investigate age-related white matter changes on magnetic resonance imaging (MRI) as an independent predictor of depressive symptoms at 1 year after controlling for known confounders.

METHOD

In a pan-European multicentre study of 639 older adults without significant disability, MRI white matter changes and demographic and clinical variables, including cognitive scores, quality of life, disability and depressive symptoms, were assessed at baseline. Clinical assessments were repeated at 1 year.

RESULTS

Using logistic regression analysis, severity of white matter changes was shown to independently and significantly predict depressive symptoms at 1 year after controlling for baseline depressive symptoms, quality of life and worsening disability (P<0.01).

CONCLUSIONS

White matter changes pre-date and are associated with the development of depressive symptoms. This has implications for treatment and prevention of depression in later life.

The role of vascular risk factors in late onset bipolar disorder

BACKGROUND

The association between late life depression and cerebro-vascular risk and cerebro-vascular disease is well established. Do similar links exist with late onset bipolar disorder?

AIMS AND OBJECTIVES

Patients with early onset (less than 60 years of age) bipolar disorder were compared with those of late onset (aged 60 and above) in relation to cognitive function, physical health and vascular risk factors.

METHOD

Cross-sectional survey of elderly bipolar disorder patients (above 65 years) involved with secondary care mental health services. Thirty patients with early onset were compared with 20 patients with a late onset bipolar disorder. Diagnosis of bipolar disorder was according to ICD-10 criteria and without an associated clinical diagnosis of dementia. Assessment of cognition included tests of frontal-executive function, and cerebro-vascular risk was quantified with the Framingham stroke risk score.

RESULTS

The late onset group had a higher stroke risk score than the early onset group, this difference persisting despite taking age and gender differences into account. However, late onset patients' cognitive function (including frontal lobe tests) and physical health status was no different to the early onset group.

CONCLUSION

There is higher 'cerebrovascular risk' in elderly patients with late onset bipolar disorder, compared to patients with an early onset. This suggests that cerebrovascular risk may be an important factor for the expression of bipolar disorders in later life, and has significant management implications for older bipolar patients.

Procoagulant stress reactivity and recovery in apparently healthy men with systolic and diastolic hypertension

OBJECTIVE

The aim of this study was to investigate whether systemic systolic hypertension (SHT) and diastolic hypertension (DHT) are associated with an exaggerated response of factor VII clotting activity (FVII:C), factor VIII clotting activity (FVIII:C), fibrinogen, and d-dimer to acute psychosocial stress.

METHODS

We performed the 15-min Trier Social Stress Test (i.e., combination of task preparation, job interview and mental arithmetic) in a sample of 42 middle-aged apparently healthy and unmedicated men with normal and elevated blood pressure (BP) (i.e. screening systolic and/or diastolic BP>or=130/85 mmHg). Blood samples for coagulation measures were obtained immediately pre and post stress and 20 min and 60 min thereafter. Repeated measures analyses of covariance controlled for age, body mass index, screening mean arterial BP, and resting level of coagulation factors.

RESULTS

There was a stress-by-DHT interaction for changes across all time points in FVII:C (P=.027), FVIII:C (P=.018), and d-dimer (P=.011) explaining between 14% and 17% of the variance. Compared to subjects without DHT, diastolic hypertensives had higher FVII:C immediately post stress (P=.085, Cohen's d=.60) and at 20-min recovery (P=.19, d=.46), higher FVIII:C at 20- (P=.028, d=.78) and at 60-min (P=.035, d=.75) recovery, and higher D-dimer at 20-min recovery (P=.10, d=.58). A significant stress-by-SHT interaction for fibrinogen (P=.050) became nonsignificant when controlling for covariates.

CONCLUSION

Diastolic hypertension exaggerated the acute procoagulant response to stress in middle-aged men. This effect was particularly observed during recovery of hypercoagulability from stress. The findings suggest a psychobiological mechanism linking stress with an increased atherothrombotic risk in hypertensive individuals.

Occult PTSD with panic attacks in a patient post-TIA: case report

Affective disorders are common sequelae of cerebrovascular events. A myriad of evidence demonstrates that clinically significant depression can often follow a stroke. However, less is known about the extent to which anxiety disorders present after these experiences, and in particular, post-traumatic stress disorder (PTSD) with panic attacks. To our knowledge, the association between transient ischemic attacks (TIAs) and PTSD with panic attacks has not been described in the literature. Here we describe a patient with depression and PTSD with panic attacks following a transient ischemic attack. Many non-psychiatric physicians learn about post-stroke depression so they are equipped to screen for it. However, to many physicians, PTSD with panic attacks usually conjures the image of an individual who experienced either trauma or rape. Therefore, it is important to increase the awareness of such complications after TIAs. Increased awareness of these TIA sequelae has important implications for detection by non-psychiatric healthcare providers. Furthermore, prompt recognition and treatment has important implications for patient quality of life.

Venlafaxine efficacy and tolerability in the treatment of post-stroke depression

OBJECTIVE

To determine the efficacy of venlafaxine in treatment of post-stroke depression.

METHODS

The sample consisted of 30 adult subjects with symptoms of post-stroke depression. All subjects received treatment with venlafaxine in therapeutic dose range in the period of three months. All subjects were assessed prior to treatment and in 1 month-follow-up and 3 months follow-up using the standardized instruments for assessment of depressive symptoms (Hamilton Depression Rating Scale HAM-D-21), and for efficacy and tolerability with the Clinical Global Impressions scale (CGI). All subjects signed an informed consent form prior to entering in the study.

RESULTS

The results indicate a statistically significant reduction of depressive symptoms following three months of treatment with venlafaxine. The difference between three assessments with The Clinical Global Impressions scale was statistically significant. Unwanted effects were registered in two of the subjects (increased blood pressure) and they were of mild intensity.

CONCLUSIONS

Venlafaxine proved to be very efficient, well tolerated and safe in the treatment of depression occurring after cerebrovascular incidents to the subjects in this study.
