Intracranial haemorrhage in patients treated with monoamineoxidase inhibitors.
The complications occurring in patients treated with monoamineoxidase inhibitors are reviewed under the headings of paroxysmal headache, cardiovascular and cerebrovascular syndromes.

Sixteen patients are described who developed intracranial haemorrhage.

Fourteen were being treated with Parstelin, and of these five were left with severe permanent neurological disability.

Two were being treated with phenelzine, and one had a permanent hemiplegia.

The importance of precipitating factors, such as a cheese meal and sympathicomimetic drugs, is discussed.

The syndrome of intracranial haemorrhage occurring in an individual who is being treated for his depression with monoamineoxidase inhibitor drugs is one which will probably decrease in frequency.
