Conventional antipsychotic drugs such as haloperidol have been supplanted by newer, atypical antipsychotics (risperidone [Risperdal], olanzapine [Zyprexa], quetiapine [Seroquel], ziprasidone [Geodon], aripiprazole [Abilify]), although no medication has an FDA indication for the treatment of behavioral symptoms in patients with dementia
The clinical diagnosis of Pick disease can be one of the most difficult facing the neurologist. Those patients found to have lobar atrophy usually present clinically with bouts of irrational behavior, bulimia, marked reductions in speech, abulia, and apathy.
In many ways, the frustration experienced bypatients struggling with mild cognitive impairment(MCI) is matched by the frustration ofclinicians facing the challenge of managing thisheterogeneous condition. The prognosis can bevariable, and no proven therapies exist.
Defined as a clinical syndrome involving progressive deterioration in multiple areas of cognitive functioning, dementia is a major cause of disability, institutionalization, and increased mortality among the elderly. Although it can occur in younger persons too, dementia is typically associated with aging. It is often seen as a disease that cannot be prevented or cured. However, there is increasing evidence that some types of dementia can be successfully treated or even reversed.
Insights Into Neuropathology Elucidated Through the Science of Sleep
In patients with dementia who are physically aggressive and dangerous to themselves or others, the use of intramuscular haloperidol or lorazepam may be appropriate. Because haloperidol causes less drowsiness and cognitive impairment than lorazepam, it is preferred in patients with dementia and delirium. The usual dose of haloperidol for elderly patients with dementia is 0.5 to 1 mg; this dose can be repeated every 25 to 30 minutes until the patient is no longer dangerous to self or others. If benzodiazepine or alcohol withdrawal is suspected, lorazepam is the preferred medication. Physical restraints may be appropriate until the medication takes effect.
Personality Traits Early Clue to Distinguishing LBD From AD. Lewy body dementia (LBD) is often difficult to distinguish from Alzheimer disease (AD) but subtleties in symptoms provide clues to the differential diagnosis.
Successful intervention for Alzheimer disease requires an early and timely diagnosis. Caregivers of persons with AD often state that an average of 2 years passes from the onset of symptoms to a formal diagnosis.
Essential tremor significantly compromises patients' professional and personal lives.
Increased plasma cortisol levels (correlated with increased hypothalamic-pituitary-adrenal axis activity) may be associated with more rapid disease progression in Alzheimer-type dementia (AD). In a study conducted at the Washington University School of Medicine in St Louis, Dr John Csernansky and colleagues assessed 33 patients with very mild or mild AD and 21 persons without AD annually for up to 4 years, using the Clinical Dementia Rating Scale and various neuropsychological tests. Plasma was obtained from each patient and assessed for cortisol level.
Given the lack of a good evidence base for pharmacological treatment of neuropsychiatric symptoms of dementia, are there any effective treatments for such problems as agitation, aggression, delusions, hallucinations, repetitive vocalizations, and wandering? A recent review suggests that nondrug interventions that address behavioral issues and unmet needs may be helpful, as may caregiving interventions and the use of bright light therapy.
Theories about the causes of Parkinson disease (PD) are as tangled as the neurofilament proteins of Lewy bodies. However, investigators are teasing out threads of evidence that increasingly implicate environmental factors--perhaps aided and abetted by genetics--as contributors to this common neurodegenerative disorder.
The second report from the Alzheimer's Disease Cholesterol-Lowering Treatment (ADCLT) trial was recently published, along with several reviews of clinical and laboratory investigations of the statins, in a theme issue of Acta Neurologica Scandinavica. The accumulated data reflect the potential of the agents to affect the onset or course of Alzheimer disease (AD), with contradictory or insufficient evidence of treatment effect.
Parkinson disease (PD) is the second most common neurodegenerative disorder among elderly persons (after Alzheimer disease [AD]), and the incidence is expected to double in the next 15 to 20 years. About a million Americans have PD which means that it is about 3 times as common as multiple sclerosis and half as common as epilepsy.
How do you know whether a patient with end-stage dementia is experiencing pain or suffering when the patient has lost the ability to communicate verbally? Experts say a clinician should have a high index of suspicion that a patient with end-stage dementia is experiencing pain or suffering.
By now, many clinical researchers and practitioners recognize the strong association between cognitive impairment and type 2 diabetes, which, in its early stages, is characterized by hyperinsulinemia and insulin resistance. Although this relationship has not been observed uniformly, more than 20 large-scale epidemiologic studies have reported a link between type 2 diabetes and in creased risk of cognitive impairment and dementia, including Alzheimer disease (AD), the most common type of dementia.
Alzheimer dementia (AD) represents a profound global health concern. By the year 2050, the prevalence of AD in the United States is expected to reach 15 million. At present, there are 4.5 million cases in the United States, which equals an estimated cost of $100 billion each year in medical and family expenses.
Many physicians, including psychiatrists, may shy away from seeing elderly patients with symptoms of dementia because they imagine that there are a large number of alternative diagnoses and that differential diagnosis is complicated. In fact, however, the number of possible diagnoses in most situations is relatively small and the diagnosis of dementia in older patients is certainly feasible in primary care psychiatry.
An unfavorable prognosis may be in store for patients who report severely disrupted sleep patterns accompanied by rapid eye movement (REM).
The numbers of patients with Alzheimer disease (AD), as well as those with severe cognitive impairment caused by traumatic brain injury and stroke, are continuing to increase. This article includes some nonconventional treatment approaches for which the evidence is limited.
While dementia is marked by such cognitive deficits as disorientation, memory loss and changes in intellectual functioning, these are not the symptoms that cause the most distress to caregivers.
The obvious sometimes bears repeating: Sick people have trouble thinking. They may be suffering from a delirium, a dementia or a more subtle disturbance of cognition caused by fever, drugs, infection, inflammation, trauma, hypoxemia, metabolic derangement, hypotension, tumor, intracranial pathology, pain and so forth.
The psychiatric community has a need for diagnostic and predictive tests. Some recent techniques have just become available for clinical care.
