ABSTRACT
The various forms of delirium separate themselves clinically into three types: First, simple febrile delirium; that is, the delirium which is a symptom and accompaniment of the various exanthemata, infectious fevers and acute visceral diseases. The foregoing paragraphs show that delirium, confusion, and stupor present much that is common, not only in their symptoms, but also in their treatment. The neurasthenic-neuropathic insanities form a group of affections having as their basis both neurasthenia and neuropathy. If the morphin has been used for a long period, more or less decided and persistent mental impairment follows; this condition is analogous to alcoholic dementia but less marked. The patient frequently presents, besides, hyperesthesias and paresthesias of the extremities. Lead intoxication, so far as the cerebral symptoms are concerned, may manifest itself either in an acute or a chronic form. In the acute form the patient presents headache, insomnia, frightening dreams, tinnitus, flashes of light, mental slowness, and depression.
