Parkinson's disease, or paralysis agitans, is a central nervous system disease. Concentrations of dopamine and acetylcholine, neurotransmitters in the substantia nigra of the basal ganglia, become imbalanced. Bradykinesia, rigidity, rhythmic head nodding, and pill-rolling motion of the thumb and forefinger are characteristic. Difficulty verbalizing, dementia, and depression are also common. Levodopa, the medication of choice, restores dopamine to brain cells, reducing parkinsonian symptoms. Awareness by the PACU nurse of the potential for systemic effects of dopamine is one important element of postanesthesia care for the patient with Parkinson's disease. In addition, recognition of the unique physical limitations and medication combinations for each patient promotes optimal postanesthesia nursing assessment and intervention.

The relation between dementia and depression in 61 adults with Down syndrome or 43 adults with mental retardation due to other causes was examined. Age-matched participants, ranging in age from 20 to 60 years, received a neuropsychological battery to assess declines in functioning and caregiver report measures to assess adaptive behavior and depression. Eight adults with Down syndrome had both depression and declines in functioning. No adults with mental retardation due to other causes had declines. Greater severity of depression was related to lower MA, poorer memory, and lower adaptive functioning in adults with Down syndrome only. Results suggest that dementia and depression are associated in Down syndrome but not in mental retardation due to other causes.

This paper invites community psychiatric nurses (CPNs) working with the elderly to examine their involvement with elderly people who are depressed. It does this by examining a selection of the more recent literature on the topic of depression in the elderly and discusses how this might inform and guide the CPN in his/her practice with this client group. Areas from within the literature which are examined in this paper are: the prevalence of depression in the elderly; problems of underdetection and undertreatment; classification; screening instruments; social factors in causation; prognosis following treatment; and psychological therapy. The literature is shown to have much to offer in aspects of CPN role such as: assessment and planning of care, including psychological therapy; liaison with, and education of, other professionals; screening; and primary prevention. The nursing literature of this CPN specialism, where it relates to depression, is also examined. Although developments in psychiatric services specifically for the elderly were mainly as a response to the illnesses causing dementia, this paper emphasizes that depression is the more common disorder in the elderly. It is suggested therefore that a CPN service should ensure that it is significantly orientated to the needs of this client group.

The Canberra Interview for the Elderly (CIE) has been developed as a field instrument for identifying cases of dementia and depression, doing so strictly according to the diagnostic criteria in both the draft ICD-10 and DSM-III-R. It has been designed to be administered by lay interviewers. Information is gathered from the subject and an informant, and is then processed by computer algorithm to generate diagnoses. In a sample of 76 elderly patients attending a hospital clinic, test-retest reliability was found to be high at the level of individual items. For the diagnoses made on two occasions, agreement was comparable with other standardized psychiatric interviews designed for lay administration in the community. Validity, other than content validity, remains to be assessed. The CIE and its diagnostic algorithms are an efficient tool for clinical and epidemiological research on dementia and depression among elderly people, where close adherence to international criteria is required.

Depression is common in patients with senile dementia of the Alzheimer type (SDAT) and may precede the onset of the dementia; the underlying biological and neurotransmitter mechanisms may be common to both diseases, so far as norepinephrine lesions are concerned. The major routes of metabolism of amines in the brain utilize the monoamine oxidase (MAO) enzymes. Due to the consistent severity of norepinephrine lesions in the locus coeruleus of patients with pre-senile dementia or SDAT and the fact that MAO-A enzyme is the major metabolizing enzyme present in the locus coeruleus in man, the new specific, reversible MAO-A inhibitors may have a place in the treatment of depression associated with SDAT.

We studied latent (mild) pulmonary encephalopathy in 14 patients with mild chronic respiratory insufficiency due to the sequelae of pulmonary tuberculosis. All of the patients were between 49 and 62 (mean age: 57.9). None of them had any impairment of daily activities and apparently had a clear consciousness. First, the P300 component evoked by auditory stimuli was examined. Immediately after that, the PO2, PCO2, pH were measured. Then the Hasegawa's dementia scale, the mini-mental state, the "Kanahiroi" test, Zung's depression score, digit span test were also assessed in the 14 patients. P300 components in 7 age-matched normal volunteers were also examined and compared with those in the 14 patients. The mean P300 latency in the patients were significantly prolonged compared with that in the normal volunteers (p less than 0.01). The P300 latency was well correlated with the PCO2, PO2, pH. The results of the "Kanahiroi" test also correlated with these parameters. We suggest that patients with mild respiratory insufficiency due to the sequelae of pulmonary tuberculosis often have latent (mild) pulmonary encephalopathy, and that P300 latency and the "Kanahiroi" test are very useful to detect and evaluate such latent pulmonary encephalopathy.

Many studies of age-related cognitive decline have failed to distinguish between usual and successful aging. Although some degree of cognitive impairment is associated with aging, when one looks at average performance, there is great variability among individuals, with many showing little or no deleterious effects of aging on intellectual abilities. Many of the risk factors for dementia and for conditions associated with cognitive impairments can be treated or controlled. Among the preventable causes of cognitive decline are the following: AIDS, Alcohol and drug abuse, Cerebrovascular disease, Exposure to organic solvents or lead, Head trauma, Overmedication, Syphilis. Other conditions that may cause cognitive decline can be controlled or treated: Atherosclerosis, Depression, Diabetes, Emphysema, High blood pressure, Obesity, Sleep disorders, Thyroid dysfunction. In addition, it may be possible to enhance the cognitive performance of even healthy elderly people through changes in diet and lifestyle. Recent data raise the possibility that improved prenatal and perinatal care and greater access to educational opportunities may result in a decreased incidence of dementia in future generations of older adults. Although they are rapidly becoming more numerous, the efficacy of cognitive training programs in preventing or slowing cognitive decline has not yet been demonstrated. Nevertheless, such programs may ameliorate cognitive impairment by reducing the psychiatric disabilities associated with anxiety and depression. The general principle underlying these strategies for limiting cognitive impairment with age is to maximize brain reserve and minimize brain damage.

Dementia, depression, alcoholism, and suicide are some of the most important mental health issues for the aging population. Among the factors that affect the physician's ability to evaluate and manage these disorders are drug-induced side effects, the ability and willingness of patients to communicate their feelings, the level of caregiver cooperation, and limitations imposed by federal regulations and reimbursement policies. In this first of three installments of a panel discussion, experts in geriatrics and geropsychiatry discuss healthy aging, age-related memory and sensory loss, changes in mentation postanesthesia, sexuality in the elderly, and side effects of common psychoactive medications.

The clinical neuropsychologic profiles of patients with Parkinson's disease and patients with SDAT show both overlap and dissociation. Speech, language, and certain memory skills are examples of dissociable differences, especially in the early stages of the disease. Furthermore the presence of depression, evidence of cognitive slowing, and absence of aphasia in patients with Parkinson's disease suggest prominent subcortical involvement. It is probably premature to categorize all of the cognitive changes in patients with Parkinson's disease as subcortical, however. Some skills, such as visuospatial and executive functions, are impaired in both disorders, and although the etiologic bases for task failure may differ for each, this issue remains open-ended. Another problem is that often the evidence for or against the cortical/subcortical distinction is insufficient and in some cases based on a single measure thought to be representative of a given cognitive domain. Most importantly there are few comparative studies that provide unequivocal support for making a cortical/subcortical distinction. Failure to equate for level of cognitive impairment or functional disability between dementias and strict adherence to cross-sectional study designs further compromise efforts to characterize each syndrome precisely. Whitehouse suggested that a prospective study of several different dementias studied in parallel, examining a wide range of cognitive skills, is required before the cortical/subcortical classification scheme can be validated. A critical component is an autopsy program to confirm diagnoses and provide clinicopathologic correlation. It is possible that the diverse nature of the cognitive impairment in patients with Parkinson's disease is not a methodologic artifact but reflects multiple disease subtypes. Ross, Mahler, and Cummings proposed three dementia syndromes in patients with Parkinson's disease: one that is relatively mild and meets the criteria for subcortical dementia, a second that is more severe and shows a wider range of cognitive impairment but is still neuropathologically distinct from SDAT, and a third severe dementia with both subcortical and cortical involvement that may reflect basal ganglia and Alzheimer-type pathology.

Losses are an integral part of chronic illness and disability. The term chronic sorrow, has been used to describe the long-term periodic sadness the chronically ill and their caregivers experience in reaction to continual losses. In this conceptual analysis of chronic sorrow, identified critical attributes are: cyclic sadness over time in a situation with no predictable end; external and internal stimuli triggering the feelings of loss, disappointment, and fear; and, progression and intensification of the sadness or sorrow years after the initial disappointment or loss. Model, borderline, related, contrary, and illegitimate cases illustrate what the concept is and what it is not. The meaning of chronic sorrow is compared to the meaning of unresolvable grief and depression. Chronic sorrow in various stages of life is illustrated in descriptions of: the situation and feelings of parents of handicapped children; multiple sclerosis patients in the middle, productive years; and elderly caregivers of spouses with dementia. Implications for research include the need to study the concept in various populations to determine its prevalence and operation. Through research, the meaning of the concept can be further clarified. This is a beginning step toward developing nursing theory that will give direction for providing care to persons encountering sadness over long periods of time.
