Vascular mania: an old concept in danger of sclerosing? A clinical overview

Type 2 diabetes mellitus is associated with manic morbidity in elderly patients with mood disorders

The association between mood disorders, especially bipolar disorder (BD), and metabolic disorders, is long known. However, to which extent metabolic disorders affect the course of mood disorders in late life is still open to inquiring. To assess the impact of type 2 diabetes mellitus (T2DM) on late-life mood disorders a retrospective chart review was performed. Elderly depressive patients (≥ 65 years) diagnosed with Major Depressive Disorder (N = 57) or BD (N = 43) and followed up for at least 18 months were included and subdivided according to the presence of T2DM comorbidity. Vascular encephalopathy (39.1% vs. 15.6%, P  = 0.021) and neurocognitive disorders (21.7% vs. 5.2%, P  = 0.028), were more frequently reported in patients with T2DM than in those without. Patients with T2DM showed a greater percentage of follow-up time in manic episodes (r = -0.23, P  = 0.020) and a higher rate of manic episode(s) during follow-up (21.7% vs. 5.2%, P  = 0.028) than those without. When restricting longitudinal analyses to patients with bipolar spectrum disorders, results were confirmed. In line with the well-known connection between BD and metabolic disorders, our data support an association between T2DM and unfavorable course of illness in the elderly with BD.

Treatment of Bipolar Disorders in Older Adults: A Review

Background

Old age bipolar disorder has been an orphan of psychiatric research for a long time despite the fact that bipolar disorder (BD)-I and II together may affect 0.5-1.0% of the elderly. It is also unclear whether aetiology, course of illness and treatment should differ in patients with a first manifestation in older age and patients suffering from a recurrence of a BD known for decades. This narrative review will summarize the current state of knowledge about the epidemiology, clinical features, and treatment of BD in the elderly.

Methods

We conducted a Medline literature search from 1970 to 2021 using MeSH terms "Bipolar Disorder" × "Aged" or "Geriatric" or "Elderly". Search results were complemented by additional literature retrieved from examining cross references and by hand search in text books.

Summary of findings

Varying cut-off ages have been applied to differentiate old age from adult age BD. Within old age BD, there is a reasonable agreement of distinct entities, early and late-onset BD. They differ to some extent in clinical symptoms, course of illness, and some co-morbidities. Point prevalence of BD in older adults appears slightly lower than in working-age adults, with polarity of episodes shifting towards depression. Psychopharmacological treatment needs to take into account the special aspects of somatic gerontology and the age-related change of pharmacokinetic and pharmacodynamic characteristics. The evidence for commonly used treatments such as lithium, moodstabilizing antiepileptics, antipsychotics, and antidepressants remains sparse. Preliminary results support a role of ECT as well as psychotherapy and psychosocial interventions in old age BD.

Conclusions

There is an obvious need of further research for all treatment modalities of BD in old age. The focus should be pharmacological and psychosocial approaches, as well as their combination, and the role of physical treatment modalities such as ECT.Appeared originally in Ann Gen Psychiatry 2021; 20:1.

Vascular Schizophrenia-like Psychosis in Older Adults

BACKGROUND

The aims of this study were to analyze prevalence and severity of vascular risk factors in older patients referred to our clinic due to onset of Very Late-Onset Schizophrenia-Like Psychosis (VLOSLP) and to create a specific phenotype based on pathophysiological insight rather than age of onset.

METHODS

In a longitudinal study, 103 (M = 39, F = 64; mean age of 80.32 ± 7.65 years) patients were evaluated with cognitive, neuropsychiatric, and functional assessment scales. Blood concentration of hemoglobin (Hb), mean corpuscular volume (MCV), platelets, total protein test (TPT), creatinine, azotemia, glycemia, total cholesterol (TC), triglycerides (TG), uric acid (UA), sodium (Na), potassium (K), chlorine (Cl), calcium (Ca), folate, vitamin B12 (Vit-B12), and homocysteine were measured. Presence/absence of tobacco use, alcohol consumption, psychoactive substance use, hypertension, hyperlipidemia, diabetes mellitus, and history of vascular disease were collected.

RESULTS

Females were more apathetic than males (NPI-Apathy: p = 0.040). Males had a significantly higher level of Hb (p = 0.019) and UA (p = 0.001), and a lower level of platelets (p = 0.004) and Ca (p = 0.003), and used more tobacco (p = 0.046) and alcohol (p = 0.024) than females. Comparing patients < 80 and ≥80 years, we found differences in frequency of vascular risk factors among men (p = 0.027). In total, 102 patients were treated for psychosis (59.16% of them were using atypical antipsychotics).

CONCLUSIONS

The results of this study could be useful for a progressive demonstration of the causal relationship between cardiac and cerebral vascular events and VLOSLP.

Poststroke Bipolar Disorder

ABSTRACT

Various diseases that impact different systems and organs in the body may trigger manic episodes. Strokes are often associated with psychiatric symptoms, particularly depressive and, more rarely, manic. We herein report a case of bipolar disorder secondary to cerebrovascular disease in a 67-year-old man with no personal or family history of psychiatric illness who, at the age of 64, had a bilateral ischemic stroke in the middle cerebral artery territory. About 20 days after this stroke, he experienced a manic episode. Three years later, he experienced a second manic episode, with another hospitalization in a psychiatric ward. With this case, we intend to emphasize that, although rare, the diagnosis of mania after stroke should not be forgotten, and most important, one should be aware of the recurrence of affective episodes just as in non-medical-caused bipolar disorder.

[Bipolar affective disorders in senescence]

Diagnostic and therapeutic measures in patients with bipolar disorders are significantly different depending on the age of those affected. Given the demographic changes and the fact that approximately one quarter of patients with bipolar disease are in old age, it is important for geriatricians to be aware of the specific aspects of bipolar disease. This review article presents the diagnostics of bipolar disorders in old people. Interactions with somatic comorbidities, which may lead to the occurrence of secondary mania, just to mention one of the characteristics of old age, are elaborated. Furthermore, age-specific differences also necessitate altered or adjusted therapy regimens, which deviate from those of younger patients.

Post-stroke emotional incontinence or bipolar disorder?

INTRODUCTION

Post-stroke emotional incontinence and bipolar disorder are two disorders that involve the dysfunction of brain structures responsible for emotional regulation. The objective of this work is to study the links between these disorders through a clinical case.

CASE REPORT

We present the case of a 43-year-old man without previous psychiatric history who experienced emotional incontinence after cerebrovascular events. He reacted promptly to selective serotonin reuptake inhibitor treatment. However, he experienced his first episode of hypomania after 6 months of antidepressant therapy. Adjunctive therapy with valproic acid and low-dose paroxetine was eventually added, resulting in complete improvement of both emotional incontinence and hypomania after 4 additional months of treatment.

CONCLUSION

The clinician should carefully explore any history of premorbid bipolar disorder, personality disorder characterized by mood instability, and family history of bipolar disorder.

Late-onset recurrent mania as a manifestation of Wallenberg syndrome: a case report and review of the literature

OBJECTIVE

The aim of the present case report was to describe the late onset of recurrent mania in a patient after ischemic injury to the cerebellum and dorsolateral medulla.

METHODS

We studied an 86-year-old male with no prior psychiatric history who developed recurrent episodes of mania following a brain stroke. Additionally, he had neurological symptom constellation typical of Wallenberg syndrome.

RESULTS

Magnetic resonance imaging of the brain revealed infarction in the inferomedial right cerebellar hemisphere and the right dorsolateral medulla in the right posterior inferior cerebellar artery (PICA) distribution. He was successfully managed with a combination of antipsychotic and mood-stabilizer medications.

CONCLUSIONS

Post-stroke mania may be one of the rare manifestations of Wallenberg syndrome. This case adds to the emerging literature on cerebellar involvement in mood regulation and pathology of mania.

Bipolar disorder after stroke in an elderly patient

The onset of bipolar disorder (BD) secondary to a stroke event is a rare clinical entity. Although it may be related to specific regions of the brain, several other factors have been linked to its expression such as subcortical atrophy or chronic vascular burden. While precise locations and cerebral circuits involved in the bipolarity expression after stroke still need to be determined, their investigation represents an opportunity to study brain function and BD etiopathogenesis. We present a BD secondary to multiple subcortical biparietal lacunar infarctions, a lacunar infarction in left putamen and an ischemic lesion at the cerebral trunk evolving the right median portion, in a 65-year-old male patient who experienced manic, hypomanic, and depressive episodes, after 6, 10, and 16 months, respectively, of the cerebrovascular events.

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.

Post-stroke mania precipitated by withdrawal of antidepressant in an elderly patient with chronic major depression

Post-stroke mania is a rare neuropsychiatric complication that is observed in less than 1% cases of stroke and is less common than depression. Growing evidence suggests that it may be associated with the specific regions of the brain, preexisting subcortical atrophy, a family history of mood disorders, and chronic vascular burden. However, the development of bipolar disorder after stroke is uncommon in a patient with chronic major depression. In this report, we present the case of an elderly woman with depression and chronic vascular burden; she experienced her first episode of mania after a lacunar infarct on the right side and the withdrawal of antidepressant therapy.

Vascular diseases and old age mental disorders: an update of neuroimaging findings

PURPOSE OF REVIEW

To review neuroimaging findings that have been reported in samples of patients with cardiovascular disorders and their association with the onset of Alzheimer's disease, vascular dementia, depression and bipolar disorder in the elderly and to highlight the implications of these findings to the knowledge about the pathophysiology of psychiatric disorders in old age, as well as their potential clinical implications.

RECENT FINDINGS

Vascular risk factors, such as hypertension, diabetes, dyslipidemia, smoking habits and heart failure, have all been associated with signs of cerebrovascular dysfunction, including structural MRI findings of signal hyperintensities, lacunes and stroke and functional imaging findings of brain regional hypoperfusion and hypometabolism. Such brain abnormalities have been found to increase the risk of onset of psychiatric disorder (depression, bipolar and dementia) in old age.

SUMMARY

As vascular risk factors are potentially modifiable when detected in midlife, the early characterization of brain changes associated with the presence of cardiovascular diseases holds promise to afford clinical applications in psychiatry, providing new perspectives for the prevention of old age psychiatric disorders.

'Bipolar disorder' in the elderly: what's in a name?

Bipolar disorder is a chronic disorder of mood which leads to episodes of either elevated mood or depression in a sizable number of adults in the community (1%). Though the prevalence rates in the elderly are lower in the community (up to 0.1%), there is significantly higher morbidity in protected environments like care homes and hospital settings where prevalence rates may be as high as 10%. Bipolar disorder in the elderly is probably heterogenous and its etiopathogenesis is complex. Bipolar disorder may be divided into two distinct subtypes, the late onset bipolar (LOB) and the early onset bipolar (EOB) groups. LOB patients tend to have a milder illness in terms of manic severity but they have higher medical and neurological burden. They also have lower familial burden of bipolar illness as compared to EOB patients. There is an increased risk of dementia and stroke in patients with late life bipolar disorder (and there may be a protective effect of lithium in preventing dementia). White matter changes, as seen by increased white matter hyperintensities on neuroimaging, are also increased, providing further evidence of cerebrovascular disease. Treatment of late life bipolar is currently based on guidelines drawn up for younger bipolar disorder patients. Good quality intervention studies are needed to estimate the possible protective effect of cognitive enhancers and/or vascular prevention strategies. This review suggests that late life bipolar disorder, particularly late onset bipolar disorder, is probably a distinct diagnostic entity compared to the younger bipolar patients as it has a different presentation, etiology and hence perhaps needs different treatment strategies.

Is computed tomography still useful as a neuroimaging tool in psychiatry?

BACKGROUND

Computed tomography (CT) has played a pivotal role in psychiatry from its inception; however with the advent of other high-resolution noninvasive neuroimaging techniques such as MRI, the field has gone through a dramatic transformation.

OBJECTIVE

This article will explore the current role of CT in psychiatry.

METHODS

An extensive search of the published literature (1970 - 2008) was conducted, employing a number of databases and terms relevant to CT and imaging.

RESULTS/CONCLUSION

At present CT is primarily used as a screening tool to exclude intracranial pathology. This is partly because it is widely available and less expensive than other imaging modalities. CT is unable to provide region-specific information like MRI and this has restricted its use in disorders in which functional disturbances are suspected, however it remains the preferred mode of investigation where gross structural abnormalities are suspected.
