Behavioral and Psychological Symptoms of Dementia (BPSD) are increasingly recognized as a major risk factor for caregiver burden, institutionalization, greater impairment in activities of daily living (ADLs), more rapid cognitive decline, and a poorer quality of life. BPSD contribute significantly to the direct and indirect costs of caring for patients with dementia even after adjusting for the severity of cognitive impairment and other co-morbidities. Research on these symptoms has indicated a complex interplay between the biological, psychological and social factors involved in the disease process. Although some psychotropic medications have shown modest efficacy in the treatment of these behaviors, their use has generated controversy due to increasing recognition of the side effects of these medications especially the antipsychotic medications. In this review, we examine the risk of cerebrovascular adverse events (CVAEs) and death with antipsychotic medications when used to treat elderly patients with dementia.

Delirium is a common neuropsychiatric syndrome in the elderly characterized by concurrent impairments in cognition and behaviors. The etiologies for delirium are often multifactorial and are due to underlying medical illnesses and/or due to medication effect. The diagnosis of delirium is often missed in elderly patients and this condition may be mislabeled as depression or dementia. Untreated, delirium can have devastating consequences in the elderly with high rates of morbidity and mortality. Available evidence indicates that early detection, reduction of risk factors, and better management of this condition can decrease its morbidity rates. In this review, we discuss the etiology, neurobiology, diagnosis, prevention, and treatments for this potentially lethal condition in the elderly.

Valproic acid and its derivatives are commonly used to treat many psychiatric conditions in the elderly. Hyperammonemia is a less common but important side effect of these drugs. The elderly patient appears highly vulnerable to this side effect of this group of medications. In this paper, we systematically review the published literature for hyperammonemia induced by valproic acid and its derivatives. We describe the three reported cases and review possible treatment strategies for this condition.

It has long been taught and believed that patients with depression and suicidal tendencies are at heightened risk of suicide as they begin to recover and their energy and motivation return. What are the data behind this enduring belief? More than a century ago, eminent clinicians noted that some patients with depression committed suicide just as their depression seemed to be improving. The clinicians went on to warn that early recovery carries a high risk of suicide. Although no studies have tracked suicide along with symptomatic change in depression, recent large-scale studies of suicide and phase of treatment do not indicate that suicide is more likely to occur early in recovery than at other times. Our forebears helpfully pointed out that patients with depression may commit suicide as they are beginning to recover. But the idea that these patients are at particular risk of suicide at this time, intuitively plausible as it is, remains to be substantiated.
