Suicide is distinct from suicide attempt, in terms of male predominance (2:1), presence of serious psychiatric morbidity, and in the choice of rapidly effective means which will not be interrupted. However 1 per cent per year, and 10 per cent overall, of those attempting will progress to completed suicide. Communication of intent is the most significant and frequent danger signal of suicide, and the attempt may be such a communication. Useful prognostic features of the attempt are the medical seriousness of the act (overdose accounts for 90 per cent of attempts, and only 25 per cent of suicides), and the psychiatric seriousness of the patient's mental state. Suicide in the absence of psychiatric illness is rare. Depression is the most common associated illness, and whereas the distinction between major and minor is probably not prognostically significant, the presence of current depression is. The lifetime risk of suicide in depressive illness is 15 per cent. The second largest contributor is alcoholism, in particular alcoholics who have experienced loss of a close personal relationship. Other significant psychiatric diagnoses include schizophrenia, organic brain syndrome and personality disorder. Suicide rates differ internationally, but the identification of significant socio-cultural risk factors is hampered by the official differences in ascertainment which exist. Although suicide rates increase with each decade of life, there has been a steady recent rise in suicide rates in many countries, which has been occurring disproportionately among the group aged 15-34.

The risks of various psychiatric illnesses among the first-degree relatives of 160 surgical control patients were estimated. Morbidity risks were calculated separately for males and females because of previous findings showing significant sex differences for certain diagnoses. The findings, based on ICD-9 criteria, demonstrate a significantly higher risk of depression, neurosis, and organic brain syndrome in females than in males. The risk of alcoholism was significantly higher in males.

Some aircraft personel and airline industry workers are exposed to jet fuel, a mixture of aliphatic hydrocarbons (petroleum 80%) and some organic solvents (petroleum 80%) and some organic solvents (aromatic hydrocarbons 20%). In order to evaluate the possible neuropsychiatric sequeale of such long-term occupational exposure, we examined 30 workers exposed at about 250 mg/m3 for 4-32 years at a jet motor factory. They were compared with two control groups (2 x 30) of matched non-exposed workers. The medical history was first assessed by standardized interviews and examination of medical records kept by the factory physician. The exposed subjects had, after their employment, much more often sought medical advice because of emotional dysfunctions, such as depression and anxiety, than had the control groups (P less than 0.005). When the prevalent mental symptoms, indicative of brain lesion, later were rated by psychiatrists, the exposed workers scored higher than did the controls (P less than 0.001). 14 subjects showing most symptoms were then selected for a thorough neuropsychiatric clinical investigation comprising psychosocial inquiries, psychological testing, personality assessment and neurological/neurophysiological examination. Seven were judged to suffer from mild organic brain syndrome (i.e. "organic neurasthenia") of which one subject was a severe case. The subjects had all undergone a slow but steady personality change over the years--starting from an ordinary strength without neurotic traits and moving towards an asthenic state with fatigue, anxiety and vegetative hyperreactivity. No other cause for this change could be identified as an alternative to the occupational exposure to jet fuel. It is concluded that personality changes and emotional dysfunctions are the foremost effects of such long-term exposure to petroleum products.

The purpose of this paper is to review psychosocial aspects of geriatric rehabilitation and suggest treatment modifications and responsibilities of physical therapists in this area. Current statistics on elderly people are given, and the implications of these statistics for future health care and the rehabilitation of elderly patients are discussed. The current literature on psychosocial theories of aging is reviewed, and implications for care are given. The additional topics covered in this overview are depression and motivation, hypochondriasis, and organic brain syndrome. This overview also describes several quick and easy assessment tools and intervention techniques that can be used in the clinical setting by physical therapists. Throughout this article, suggestions are made from a psychosocial focus for the role of the physical therapist in geriatric rehabilitation.

Sleep disorders are difficult to distinguish from changes in sleep typically occurring after age 60. Sleep laboratory evaluation is needed to differentiate normal sleep alterations from the similar but more severe symptoms of depression or organic brain syndrome, and to detect sleep apnea, the most common sleep disorder found in geriatric patients. This disorder may be fatal, especially if a hypnotic drug is prescribed. Since biologic rhythms are easily disturbed in the elderly, education about sleep habits may be the most helpful therapy.

The relationship between depression and complaints of physical disease in the elderly is often discussed but has received little documentation. The authors administered questionnaires to 88 elderly volunteers to assess two common psychologic diagnoses, affective disorders and organic brain syndrome, and three common cardiovascular symptoms, pain or numbness in the jaw or arm, pressure in the chest, and difficulty in breathing. Data on utilization of health care professionals and demographic information were also obtained. A significant correlation between reports of depression and complaints of cardiovascular symptoms was seen. While the volunteers with depressive symptoms also visited their physicians more often than did the other volunteers, they did not seek the help of mental health professionals. This raises the larger issue that elderly persons who have mild to moderate depression present to our health care system.

Although an association of psychiatric symptoms with vitamin B12 deficiency is well accepted, the incidence and nature of these symptoms is not established. To help illuminate the natural history of this illness we review the literature regarding psychopathology associated with B12 deficiency and examine 15 cases, including one of our own, that meet specified criteria for B12-responsive psychosis. In the accepted cases the most common psychiatric symptoms were organic brain syndrome, paranoia, violence, and depression. Several of the patients were not anemic and had no neurologic deficit. Examination of blood smears or obtaining of serum B12 levels should be considered for patients with the symptoms described.

A case of acute paranoia in a 64-year-old woman with a previous history of one depressive episode is described. Accurate diagnosis was hampered by her illogical and tangential answers to questions and the development of an organic brain syndrome while on neuroleptics and anticholinergics. She did not tolerate tricyclic antidepressants and was unresponsive to three electroconvulsive therapy (ECT) treatments. Because of the previous history of depression and the presence of some depressive symptoms, the possibility of a depression underlying her paranoid psychosis was considered. A dexamethasone suppression test (DST) was performed to confirm this and was found to be abnormal. ECT was then continued with the eventual result of complete remission in symptoms. The authors discuss the potential usefulness of the DST in confirming a diagnosis of depression in selected cases of late onset psychosis.

In two studies, 145 psychiatric inpatients were each asked to say 100 numbers in random order, using the numbers 1 through 10. Compared with normative data, patients with personality disorders and neuroses were not impaired on the random number generation (RNG) task and patients with chronic alcoholism and primary affective disorder, depression, were significantly imparied, but not as much as those with schizophrenia and organic brain syndrome. The relationship between RNG performance and psychiatric diagnosis may reflect severity of disturbed cognitive functioning. The Randomization Index was sensitive to changes in symptoms during hospitalization. The RNG task provides a brief objective measure of those components of attention, cognitive capacity, and short-term memory that are affected by severity of psychopathology.

An analysis of 151 psychiatric consultations at a large publicly supported teaching hospital indicated that referral rates were greater from the medical services as compared with the surgical services. Minorities, elderly, and widowed persons were underrepresented. Depression and organic brain syndromes were the most common diagnoses and the presence of an organic brain syndrome had been frequently missed by the referring physician.
