Psychiatric dilemmas in Australian aborigines.

Many workers have pointed out that there is a great need for training aboriginal workers to become involved in the psychiatric problems of their community. However, it sometimes occurs that such workers are regarded with suspicion and are often disturbed by the act of working among their own people. It would appear that the principle psychiatric illnesses seen in the rest of mankind are also recognizable in the Australian aborigines, but these currently represent only a minority of the mental health problems encountered. One important role of the psychiatrist, therefore, is to contribute to the understanding of the overall problem. There are several ways in which he can do this. One is to inform the rest of the Australian community that aboriginal problems are not due to stereotyped behaviour--stupidity, laziness or purposeful deliberation--and that aborigines are not basically aggressive and that their problems should be seen as a disorder of adjustment and adaption failure. The psychiatrist should strive to continue educating members of the community for the specialized nature of the task required.

Alcoholism

The effect of beta adrenergic blocking drugs on speakers' performance and memory.

Propranolol 40 mg was compared with a matched placebo tablet in its effect on the performance of anxious and non-anxious human volunteers. Subjects were required to give a brief speech, which was video-taped and later rated by trained observers for signs of anxiety; propranolol clearly reduced rated anxiety in the non-verbal behaviour of anxious subjects, as well as the anxiety observed in the speech of the anxious compared to the non-anxious. It also affected self-reported anxiety in the anxious, and reduced the pulse rate of anxious and non-anxious alike. Subjects were also prompted, by being given the first letter, to recall both difficult and easy words, drawn from selected verbal categories; propranolol impaired recall of difficult items in the memory of anxious subjects. Results were interpreted as showing a central as well as peripheral role for propranolol in blocking adrenergic receptors' activity in anxiety.
