Psychiatry's renewed interest in its identity as a medical specialty and its increased therapeutic armamentarium make its involvement with chronically medically ill patients more feasible than ever before. These patients face problems which include economic ones, conflicts between independency and dependency, those connected with self-image, intra-family stresses including sexual ones, social isolation and the threat of death. Patients respond to these stresses with psychological symptomatology which includes depression, suicidal behavior, anxiety, delirium, dementia and psychosis. The treatment of the consequences of these stresses is the daily work of the liaison psychiatrist.

Perception, attention and recall were measured in geriatric subjects and patients suffering from dementia, Korsakov's psychosis or depression. Dementia patients were unable to perceive, attend and recall; depressed patients were unable to attend; and patients with Korsakov's psychosis were unable to attend and recall. Perception, attention and recall were correlated in the normal group but not in any one patient group. Traditional assumption of the interdependence of these functions may not be applicable to these patients. Demented patients show a different pattern of cognitive disability than age-matched controls.

Forty-seven subjects (19 elderly dements, 18 elderly depressives, 10 elderly physically ill) were given a continuous false recognition technique (FRT) in a test battery including a measure of short-term memory and the Kendrick Synonym Learning Test. Results were analysed according to signal detection theory and interpreted in terms of an encoding breakdown. Depressives were found to be characterized by conservative error-free performance whereas the demented made more errors, partly because of their more liberal criterion and partly because of their greater loss of encoding characteristics. From these results, an optimal cut-off score was chosen for differential diagnosis using the FRT. This was shown to hold more promise than the SLT in discriminating between dementia and depression.

As expected, dements, depressives and patients with a mixed psychopathology were differentiated from one another on the sedation threshold measure and on a number of psychological tests. In depressives responding to treatment significant changes in physiological and psychological measures, which had been reported in an earlier study could not be replicated except for an increase of psychomotor speed. In the present sample of patients there were significant correlations between various psychological measures and between them and the levels of the sedation threshold, suggesting that sedation thresholds and psychological tests measured related cerebral functions. Evidence obtained from the earlier investigations to the effect that cerebral age changes short of those occurring in dementia may facilitate the occurrence of depression in late life was only weakly confirmed by the replication study.

Necropsy brain tissue from normal (control) patients and patients with depression and dementia was examined for activities of various cholinergic components, and these related to the degree of senile plaque formation and extent of intellectual impairment. Choline acetyltransferase and acetylcholinesterase activities decreased significantly as the mean plaque count rose, and in depressed and demented subjects the reduction in choline acetyltransferase activity correlated with the extent of intellectual impairment as measured by a memory information test; muscarinic cholinergic receptor binding activity remained unchanged with increasing senile plaque formation but butyrylcholinesterase activity increased. The results suggest a close relation between changes in the cholinergic system and Alzheimer's dementia, but the precise role of the system in this disease remains to be elucidated.

The hypochondriacal patient presents numerous frustrations for the physician. The typical hypochondriac is a middle-aged person dominated by a preoccupation with bodily symptoms. Bereavement, serious life failures, and severe blows to self-esteem put patients at high risk for somatization. Hypochondrisis has been cited as a symptom of masked depression, early paranoid schizophrenia, and dementia and/or delirium. A careful diagnostic work-up with attention to any correctable psychiatric illness sets the stage for regularly scheduled, long-term supportive therapy.

As part of a study of long-term institutional care of the elderly, this report presents a comparison of the characteristics, health problems, and state of mind of 193 elderly applicants for such care (Group A) with those of 141 elderly persons living independently in the community (Group I). Group A members were older, living with a spouse less often, and had low incomes. They showed much more cerebrovascular disease, incontinence, recent loss of independence in the activities of daily living, dementia, recent hospitalization, loneliness, and depression. They had had much less recent involvement in social and recreational activities, although most had not been socially isolated. They had received more extensive help from relatives and friends, and it seemed unlikely that additional help from these sources would keep many more of these elderly persons out of institutions. Community agencies and services had been used by a relatively low proportion of Group A, and hardly at all by Group I.

Normal pressure hydrocephalus (NPH) may suggest its presence by behavioral symptoms. Initally, the symptoms often manifest themselves as depression with marked psychomotor retardation. Older patients without a prior psychiatric history who have soft, nonlocalizing neurological signs and fluctuating cognitive and memory deficits in association with prominent affective and/or psychotic symptomatology of recent onset, such as the case reported here, should raise the clinician's index of suspicion. In such cases, the Halstead-Reitan neuropsychological battery may be helpful in differentiating an underlying dementia from a primary psychological dysfunction. When the presence of a dementing process is suspected, etiological diagnosis should be vigorously pursued with a CAT scan and, as indicated on clinical grounds, confirmatory and further delimiting studies such as pneumoencephalography, ventriculography, RISA scanning, electroencephalography, constant-infusion manometric testing, and/or angiography. Treatment of NPH includes one of several forms of shunting procedures and appropriate neuroleptic therapy for behavioral symptoms. Althoug there is a substantial risk (40 to 50 percent)ioral symptoms. Although there is a substantial risk (40 to 50 per cent) of shunt-related complications, as many as 60 per cent of operated patients will show objective imprvement, making the diagnosis of and referral for appropriate surgical treatment of NPH an important challenge for the psychiatrist.

Forty-two gastrectomized patients (mean age 56 years) with a serum B12 level less than 200 pg/ml were studied by psychological testing and electroencephalography. A total of 50 per cent exhibited mild to moderate or more severe intellectual impairment, judging by the history and psychological testing. EEG abnormalities were found, mainly in the form of reduced dominant activity, in 48 per cent. The results of psychological testing were in accurate conformity with the findings of dementia due to other reasons. The characteristic findings were depression and lability of affect, with a high frequency of suicidal attempts (20 per cent). We interpret the cerebral abnormalities as a result of vitamin B12 deficiency.

Normal pressure hydrocephalus (NPH) is a surgically correctable syndrome of progressive dementia, gait abnormalities, and urinary incontinence resulting from an occult hydrocephalus in association with normal cerebrospinal fluid pressure. Occurring most frequently in midlife and often idiopathic in origin, the early course of the illness may be characterized by symptoms of apathy, inattentiveness, agitation, and poverty of thought which mimic a depressive illness and may delay the recognition and treatment of the underlying structural defect. A review of the literature reveals that this association of depressive symptomatology and NPH has received little attention in the psychiatric literature, and the authors describe a case of NPH which presented as a severe, agitated depression. Clinical findings which suggest the presence of NPH are discussed, and the need to include NPH in the differential diagnosis of depression in the presenium is emphasized. The authors believe such diagnostic vigilance is necessary if the needless deterioration of potentially salvageable individuals is to be prevented.
