The origin of the psychiatric illnesses observed in drug abusers is often unclear. This study examines the causal relation between drug abuse and specific psychiatric disorders. Fifty-one male veterans first seen in 1972, who were admitted at least once per year for six consecutive years for inpatient drug-abuse treatment, underwent psychiatric assessments at each admission. Eleven men mainly used stimulants, 14 depressants, and 26 opiates. Initial psychiatric examinations showed low symptom levels in all groups but no statistically significant differences among them. By the end of six years, five of the stimulant users had psychoses, and eight of the depressant users had serious depression. The narcotics users showed no change in psychopathology. Differences between the groups were significant at the 0.01 level. These changes were not due to acute toxic reactions, but our data suggest that abuse of particular drugs has a major role in the development of specific psychiatric illnesses. The possibility that different preexisting personality disorders lead to different kinds of drug abuse cannot be excluded.

Dr. Brown traces the history of America's federal mental health program from its beginning in the early 1900s. NIMH, the institute he currently directs, was established in 1946 for the treatment and prevention of mental and emotional illnesses through research,training, and services. It is now one of the institutes of the Alcohol, Drug Abuse, and Mental Health Administration of the Department of Health, Education, and Welfare. Dr. Brown describes its continuous progress toward providing high-quality mental health care to the entire population, and discusses priorities for the future that include continuation of research on schizophrenia and depression and research that will benefit children and the elderly.

Of 54 male psychiatric patients undergoing dexamethasone suppression tests in a clinical setting, 40% of those with a major depressive disorder showed escape from suppression over the 24 hours after dexamethasone administration, while all of the patients with schizophrenia, neurosis, alcoholism,and drug abuse showed normal pituitary-adrenal suppression. Only 10% of the depressed patients showed resistance to suppression 8 hours after dexamethasone administration. There was no difference between depressed patients who did and did not show escape from suppression in type of previous episodes, family history, symptoms, or medication. However, those who showed escape tended to respond better to treatment and to be rated as having a more severe depression. The theoretical and clinical implications of these findings are not yet clear.

This paper examines the relationship between drug abuse and suicide. It attempts to assess the extent of suicidal thoughts or behaviors among a group of drug abusers. The research examines variables related to self-destructive or self-endangering behaviors, such as accidental overdoses, arrests for driving under the influence, and auto accidents in which the subject was the driver. These data were examined in relation to reports of suicidal thoughts and actual suicide attempts. The results indicate a suicide attempt rate at least 12 times greater than expected for the general population. The results also indicate significant correlations between suicidal thoughts and suicide attempts, suicidal thoughts and nonsuicidal overdoses, and arrests for driving under the influece of drugs or alcohol and nonsuicidal overdoses. The implications of these results along with the role of depression as discussed.

The authors evaluate the clinical and research significance of the diagnosis of secondary depression by comparing 48 cases of primary and 26 cases of secondary depression. The patients with secondary depression have a higher familial prevalence of alcoholism, affective disorder, and drug abuse. The groups differ somewhat on a few sociodemographic, behavioral, and attitudinal variables but are similar in symptomatology, sex ratio, onset and duration of symptoms, treatment received, and response to treatment. These results suggest that the distinction between primary and secondary depression should be retained in research that examines neurochemistry or genetics. Primary and secondary depression appear to be identical from the persepctive of clinical care. Management of these patients should emphasize the diagnosis of depression rather than antecedent diagnoses.

The authors evaluated the incidence of depression in a sample of 202 Viet Nam veterans an average of 28 months after their return from Viet Nam. Approximately one-third of the sample fell within the clinically depressed range of the Beck Depression Inventory. Comparison of the depressed and nondepressed groups indicated that the former had higher frequencies of drug abuse (particularly while in Viet Nam), more marital difficulties, a higher unemployment rate, and more current legal problems. This high incidence of depression, coupled with the finding that few of these men were being treated for the illness, indicates the need for an outreach approach to this population.

The psychopharmacology of electrical self-stimulation of the lateral hypothalamus was studied using 6-hydroxydopamine, alpha-methyltyrosine, U-14, 624, and d-amphetamine. Reduction of brain dopamine, but not norepinephrine, with 6-hydroxydopamine produced an acute depression of responding which eventually recovered to pretreatment levels. A low dose of alpha-methyltyrosine, which did not affect responding in control rats, significantly depressed responding in the rats with brain dopamine reduced. This treatment did not alter responding of rats with norepinephrine reduced by 6-hydroxydopamine. A dopamine-beta-hydroxylase inhibitor, U-14, 624, depleted norepinephrine an additional 70% yet failed to alter self-stimulation in any of the groups. In other experiments, the 6-hydroxydopamine treatment which reduced brain dopamine was found to block the facilitation of self-stimulation produced by d-amphetamine. This facilitation of lateral hypothalmic self-stimulation was not influenced by treatments which reduced brain norepinephrine. An experiment suggesting that dopamine is of importance to locus coeruleus self-stimulation is also described. Implications of these data indicating a role for dopamine in self-stimulation responding are discussed in relation to the "catecholamine hypothesis of self-stimulation".

The existence of depression in young individuals has often been denied or at least underestimated particularly during adolescence, to the benefit of such other concepts as morosity, inherent in this period of life, and from which depression should be differentiated. Recent epidemiological investigations in the general population have revealed an approximate 2% and 10% prevalence of depression in the child and the adolescent, respectively. This considerable increase in morbidity is associated with a modification of the sex ratio: more boys are affected before puberty, more girls after puberty. In the present work we shall first deal with the semiology and comorbidity of depression as related with the developmental changes occurring in the child and the adolescent. Thus, several studies have shown that the DSM III criteria for affective disorders are consistently applicable to pre-puberty children and adolescents as well. However, depression in the pre-puberty children may be more ostentatious, manifesting itself by psychomotor agitation, somatic complaints and anxiety comorbidity of the type: Separation Anxiety Disorder and phobias. Depressed adolescents may exhibit more anhedonia, more depressive cognition, hypersomnia, weight variations, more alcohol or drug abuse and suicide attempts, and, in one third of them, greater coexistence of anxiety disorders or behavioural disorders. The course of depression at this age is now known, owing to catamnestic studies that proved methodologically satisfactory (we personally managed the follow-up of 75 depressed adolescents over an average 45 months). Depression in the child and the adolescent is not a benign affection, it is a long-lived, recurrent and disabling illness.(ABSTRACT TRUNCATED AT 250 WORDS)

In this prospective, 1-year study, 360 males admitted to an inpatient alcoholism treatment program were administered a DSM-III compatible structured interview and subtyped by co-occurring psychiatric disorder. Forty percent satisfied diagnostic criteria for alcohol dependence while 27% met criteria for alcohol dependence and one additional psychiatric syndrome. The dually diagnosed patients were divided into: alcohol dependence plus drug abuse, alcohol dependence plus antisocial personality and alcohol dependence plus depression. These subtypes were compared on multiple dimensions at intake and at 1-year follow-up. At follow-up, all groups showed significant improvement in drinking and psychosocial functioning. The results suggest that subtyping alcoholics by co-morbid psychiatric disorders may be a good postdictor of clinical history, but a poor predictor of drinking outcome.

We present an analysis of all psychiatric consultations with inpatients in the somatic wards at the Central Hospital in Alesund over a period of three years. About 1% of the patients were referred for psychiatric consultation. Most of these patients had no previous experience of psychiatry. Mean age was 45 years (range 16-90), and 56% were females. The reasons for referral were assessment of suicidal behaviour (47%), depression (16%) and psychosis (11%). The most common psychiatric diagnoses were personality disorders (16%), affective disorders (14%) and alcohol and drug abuse and dependence (14%). About 10% were admitted to psychiatric wards, and 21% were referred to psychiatric outpatient clinics. The referring physicians were satisfied with the psychiatric consultation service.
