The neurology of affective disorder and suicide

Immediate psychological distress in quarantined patients with COVID-19 and its association with peripheral inflammation: A mixed-method study

Since the end of 2019, Corona Virus Disease 2019 (COVID-19) has been the cause of a worldwide pandemic. The mental status of patients with COVID-19 who have been quarantined and the interactions between their psychological distress and physiological levels of inflammation have yet to be analyzed. Using a mixed-method triangulation design (QUAN + QUAL), this study investigated and compared the mental status and inflammatory markers of 103 patients who, while hospitalized with mild symptoms, tested positive with COVID-19 and 103 matched controls that were COVID-19 negative. The severity of depression, anxiety, and post-traumatic stress symptoms (PTSS) was measured via an on-line survey. Using a convenience sampling technique, qualitative data were collected until the point of data saturation. In addition, a semi-structured interview was conducted among five patients with COVID-19. Peripheral inflammatory markers were also collected in patients, both at baseline and within ± three days of completing the on-line survey. Results revealed that COVID-19 patients, when compared to non-COVID controls, manifested higher levels of depression (P < 0.001), anxiety (P < 0.001), and post-traumatic stress symptoms (P < 0.001). A gender effect was observed in the score of "Perceived Helplessness", the subscale of PSS-10, with female patients showing higher scores compared to male patients (Z = 2.56, P = 0.010), female (Z = 2.37, P = 0.018) and male controls (Z = 2.87, P = 0.004). Levels of CRP, a peripheral inflammatory indicator, correlated positively with the PHQ-9 total score (R = 0.37, P = 0.003, Spearman's correlation) of patients who presented symptoms of depression. Moreover, the change of CRP level from baseline inversely correlated with the PHQ-9 total score (R = -0.31, P = 0.002), indicative of improvement of depression symptoms. Qualitative analysis revealed similar results with respect to patient reports of negative feelings, including fear, guilt, and helplessness. Stigma and uncertainty of viral disease progression were two main concerns expressed by COVID-19 patients. Our results indicate that significant psychological distress was experienced by hospitalized COVID-19 patients and that levels of depressive features may be related to the inflammation markers in these patients. Thus, we recommend that necessary measures should be provided to address depression and other psychiatric symptoms for COVID-19 patients and attention should be paid to patient perceived stigma and coping strategies when delivering psychological interventions.

Mania and stroke: a systematic review

BACKGROUND

Mania is a rare consequence of stroke and according to the sparse published information it is difficult to describe its demographic, clinical and prognostic characteristics.

METHODS

We performed a systematic review of all cases of mania and stroke to describe those characteristics. Studies were identified from comprehensive searches of electronic databases, reference lists of the studies collected and handbooks. Two authors independently assessed abstracts, and collected and extracted data.

RESULTS

From 265 abstracts, 139 were potentially relevant. For the first analysis, which tries to answer the clinical question of the relationship between mania and stroke, 49 studies met the inclusion criteria and described 74 cases. For the second analysis, we looked for an explicit temporal and causal relationship between manic symptoms and stroke, and selected 32 studies describing 49 cases. In both analyses, the typical patient was male, without a personal or family history of psychiatric disorder, with at least one vascular risk factor, but without subcortical atrophy and had suffered a right cerebral infarct. The majority of patients (92%) presented elevated mood as the first symptom. The other frequent symptoms were an increased rate or amount of speech (71%), insomnia (69%) and agitation (63%).

CONCLUSIONS

Post-stroke mania should be considered in any manic patient who presents concomitant neurological focal deficits and is older than expected for the onset of primary mania. The results of a systematic study of mania in acute stroke with subsequent follow-up and data from diffusion MR or perfusion CT in a multicenter study with a central database would be relevant.

Association of seropositivity for influenza and coronaviruses with history of mood disorders and suicide attempts

BACKGROUND

Anecdotal reports of mood disorder following infection with common respiratory viruses with neurotropic potential have been in existence since the last century. Nevertheless, systematic studies on the association between these viruses and mood disorders are lacking.

METHODS

Influenza A, B and coronavirus antibody titers were measured in 257 subjects with recurrent unipolar and bipolar disorder and healthy controls, by SCID. Pearson's χ² tests and logistic regression models were used to analyze associations between seropositivity for coronaviruses, influenza A and B viruses and the following: a) history of recurrent mood disorders b) having attempted suicide in the past c) uni- vs. bi-polarity and d) presence of psychotic symptoms during mood episodes.

RESULTS

Seropositivity for influenza A (p=0.004), B (p<0.0001) and coronaviruses (p<0.0001) were associated with history of mood disorders but not with the specific diagnosis of unipolar or bipolar depression. Seropositivity for influenza B was significantly associated with a history of suicide attempt (p=0.001) and history of psychotic symptoms (p=0.005).

LIMITATIONS

The design was cross-sectional. Socioeconomic factors, inflammatory markers, and axis II psychopathology were not assessed.

CONCLUSIONS

The association of seropositivity for influenza and coronaviruses with a history of mood disorders, and influenza B with suicidal behavior require replication in larger longitudinal samples. The need for these studies is additionally supported by the high incidence of these viral infections, the high prevalence of mood disorders, and resilience of suicide epidemics.

Suicide in patients with Parkinson's disease. An epidemiological study

The purpose of this study was to estimate the risk of suicide for patients with Parkinson's disease (PD) in Denmark compared with that in the background population. The study involved 458 patients with a PD diagnosis, 226 men and 232 women. The follow-up period to either death or end of follow-up on December 31, 1990 was 0 to 17 years, mean 5.7 years. Deaths in the follow-up period amounted to 254, 135 men and 119 women. Two women committed suicide. The number of expected suicides was 1.06 for men and 0.55 for women, a total of 1.62. Neither for men nor for women was the difference between expected and observed suicides statistically significant.

Suicide and multiple sclerosis: an epidemiological investigation

In a nationwide investigation the risk of death by suicide for patients with multiple sclerosis (MS) was assessed using records kept at the Danish Multiple Sclerosis Registry (DMSR) and the Danish National Register of Cause of Death. The investigation covers all MS patients registered with DSMR with an onset of the disease within the period 1953-85, or for whom MS was diagnosed in the same period. Fifty three of the 5525 cases in the onset cohort group committed suicide. Using the figures from the population death statistics by adjustment to number of subjects, duration of observation, sex, age, and calendar year at the start of observation, the expected number of suicides was calculated to be nearly 29. The cumulative lifetime risk of suicide from onset of MS, using an actuarial method of calculation, was 1.95%. The standard mortality ratio (SMR) of suicide in MS was 1.83. It was highest for males and for patients with onset of MS before the age of 30 years and those diagnosed before the age of 40. The SMR was highest within the first five years after diagnosis.

Changing patterns of suicide in Australia

This paper examines the suicide trends in Australia from a sociological perspective using a selected number of sociological variables. Our aim is not to minimize the importance of psychogenic factors in suicide but to highlight its sociological aspects. The analysis of suicide trends shows that the overall suicide rate in Australia has remained fairly stable over the past one hundred years. This outward stability, however, camouflages some important internal changes in the suicide trends in Australian society. The paper examines some of these trends and provides a profile of some of the possible sociological factors which appear to have influenced the suicide rates of men and women in Australian society between 1880 and 1985.

Depressive disorder associated with physical illness. The impact of stroke

The consultation-liaison psychiatrist is confronted time after time with depression in the context of physical illness, and the link between the two is of practical and theoretical interest. In addressing this topic, current classification systems are ambiguous. The advent of research diagnostic criteria and the primary/secondary depression dichotomy have not clarified the problem as was hoped. The conventional view that physical illness only precipitates depression in the genetically predisposed has been challenged by recent studies in patients with stroke. These studies point to a specific role for factors such as lesion location, severity of disability, and social support. In addition, the process of adjustment to serious physical illness can be understood in terms of personal vulnerability including low self-esteem, conflict within close relationships (particularly marital), and negative experiences in the developmental history. Acting on this vulnerability is the stressful life event (e.g., illness) that can have particular force if "matched" to the subjects existing psychologic conflicts. A modifying factor on the outcome of the adjustment is the influence of social support in protecting the individual from the life event. A list of potential factors influencing the occurrence of depression with physical illness is proposed. Variables likely to have an important place include 1) family history of psychiatric disorder, 2) a past personal history of depression, 3) the premorbid personality, 4) the impact of life events including the illness, 5) the degree of disability from the illness, 6) the presence of brain pathology and neuroendocrine abnormalities, and 7) the quality of social support during the time of illness.(ABSTRACT TRUNCATED AT 250 WORDS)

Research diagnostic criteria (RDC) mental disorder and self-reported symptoms in outpatients with complex partial seizures (CPS)

Fifteen outpatients with complex partial seizures (CPS) were investigated to assess the presence and severity of affective disorders, anxiety, and cognitive deficits. Forty percent of patients met the criteria for an affective disorder according to Research Diagnostic Criteria (RDC). Patients scored significantly higher than controls on the Beck Depression Inventory (p less than 0.001), on the State and Trait Anxiety Inventory (p less than 0.01, p less than 0.05), on the Symptom Questionnaire scales for anxiety (p less than 0.005), depression (p less than 0.01), and somatization (p less than 0.01). They also scored significantly lower than controls on the Mini-Mental State Examination for grading cognitive state (p less than 0.05). Epileptic patients with RDC diagnosis of depression reported significantly more symptoms of depression, anxiety, somatization, and less sociability and trustfulness than epileptic patients without concurrent mental disorders. Implications of these results are discussed.

Depressive illness as a presentation of primary lymphoma of the central nervous system

A 65-year-old man was referred from a medical unit for psychiatric assessment of a depressive illness associated with intermittent vomiting. No organic disorder was identifiable after the initial clinical examination and extensive investigations. A primary lymphoma involving the limbic system was eventually detected on repeat CAT scan and was confirmed at autopsy. This tumour, which is increasing in incidence, is notoriously difficult to diagnose and frequently presents with combined psychological and organic symptoms. It may be radiosensitive if detected early enough.
