In a double-blind 28-day comparison of alprazolam, diazepam and placebo, alprazolam 1.5-3 mg/day was of equivalent anxiolytic effect to 15-30 mg diazepam/day and there was some evidence of antidepressant activity by alprazolam, but not diazepam, in neurotic depression. No serious side-effects or laboratory abnormalities were encountered.
The potential of drugs to do harm as well as good is nowhere more critical than in the treatment of organic brain syndromes. Appropriate management of different clinical situations may require particular drugs to be used, withheld, or withdrawn. This article offers guidance in making these difficult decisions.

The anxiolytic effects of alprazolam, a triazolobenzodiazepine, were evaluated in a double-blind 28-day comparison with diazepam and placebo in 46 out-patients suffering from anxiety states of moderate to severe intensity. Alprazolam 1.5-3 mg per day was found to be of at least equivalent anxiolytic effect to 15-30 mg diazepam per day, and there was evidence of antidepressant activity by alprazolam, but not diazepam, in neurotic depression. Side-effects occurred least often with alprazolam and were minor in nature. Laboratory data showed no changes attributable to alprazolam even in a patient who swallowed 15 capsules (7.5 mg). It was concluded that alprazolam is a safe and effective anxiolytic which is well-tolerated and also shows some antidepressant activity.
This review aims to collate some of the extensive literature on the schizophrenia-like psychoses occurring in association with organic cerebral disorders. Their relationship to "true' schizophrenia is considered clinically, genetically and conceptually. The conclusions reached are as follows: The association of many organic cerebral disorders with schizophrenia exceeds chance expectation. Although there may be group differences, these psychoses include a range of symptoms similar to those found in the general run of psychoses diagnosed as schizophrenia. These psychoses usually occur in patients without genetic loading for schizophrenia. Organic cerebral disorder occurs in a substantial minority of patients diagnosed as schizophrenic and is of particular importance in the psychoses of childhood and old age. The site of the brain lesion is more important than the predisposition of the patient in the genesis of these psychoses, and lesions in the temporal lobe and diencephalon are of particular significance.

Ten patients, 5 male and 5 female, with bipolar psychosis beginning before the age of 16 years, mean 14.1 years, are described. Difficulties in diagnosis in this age group are discussed and background factors of possible aetiological importance analysed. Lithium therapy was effective in 6 out of 7 patients.

Comparison of 726 admissions to Newcastle upon Tyne General Hospital for attempted suicide in the period 1 October 1966 to 30 September 1969 with a previously reported series of 276 in 1962-4 showed an overall increase in annual admissions of 77%. For both sexes under age 30 years and females over 60 years the increase was over double. Psychiatric morbidity had increased, and there was also a significant rise in the proportion of unemployed men.The relative frequency of ingestion of non-barbiturate psychotropic or hypnotic drugs and barbiturates had changed, the former now being more common than the latter as the suicidal agent. Finally, there had been a significant increase in the proportion of patients receiving subsequent psychiatric treatment.

A within-subject comparison of the effects on the overnight sleep EEG of 1 tablet of Mandrax (containing methaqualone base 250 mg. and diphenhydramine hydrochloride 25 mg.) and 200 mg. Tuinal (equal parts of quinalbarbitone sodium and amylobarbitone sodium) in 14 normal subjects is reported.Mandrax-induced sleep was not significantly different from natural sleep in the duration of light, moderate, deep and REM phases. Tuinal produced a significant reduction in REM sleep (P < 0.01) compared with natural sleep and with Mandrax-induced sleep.
