In low concentrations, the lipid-soluble cholinesterase inhibitors cause diffuse activation on the electroencephalogram and a subjective alerting response. In higher concentrations, they cause generalized convulsions, which may be followed by coma and respiratory arrest. 

Glucocorticoids have important effects on the nervous system. Adrenal insufficiency causes marked slowing of the alpha rhythm of the electroencephalogram and is associated with depression. Increased amounts of glucocorticoids often produce behavioral disturbances in humans initially insomnia and euphoria and subsequently depression. Large doses of glucocorticoids may increase intracranial pressure (pseudotumor cerebri).

A 28-year-old man, without a psychiatric history, developed a paranoid psychosis. He had been taking levamisole twice a week in an unspecified dose for 2 years for a stage 4 melanoma and metastatic lymph nodes in the axilla. Physical examination, a CT scan, an electroencephalogram, and standard laboratory tests were all normal. He was treated with perphenazine, with partial success, but after tapering of the dose his symptoms reappeared. It was thought likely that the psychosis had been caused by levamisole, which was discontinued. Three weeks later he had recovered completely. Levamisole was not reintroduced. 

Daily doses of 1 000 000 pg RE of vitamin A can cause acute symptomatic psychosis, with striking disturbances in the electroencephalogram and pathological changes in the cerebrospinal fluid (677). After withdrawal of vitamin A and administration of low doses of neuroleptic drugs the psychotic symptoms disappeared within a week.

In the 1950s Cooke [135] and Dow [136] described their work in rats and primates showing that stimulation of the cerebellum had effects on the electroencephalogram and the frequency of seizures. On this basis, in 1973 Cooper and colleagues reported the use of chronic cerebellar stimulation in patients with epilepsy. They also reported benehts for spasticity [119]. Unfortunately, several subsequent clinical series were unable to replicate Cooper s results with epilepsy [137]. Also in the 1970s, Chkhenkeli reported preliminary results of stimulating the caudate nucleus for epilepsy (followed in 1997 by a larger series) (Chkhenkeli and Chkhenkeli, 1997).

They have shown that the biological half-life of certain radio-actively labelled vitamins was shorter than expected. Biochemical evidence of deficiency occurred as early as seven days, and abnormalities in electroencephalograms and electrocardiograms appeared in less than three weeks on a deficient diet (Canham et al.,... 

Even minor disturbances in cerebral function may be associated with gross changes in the electroencephalogram, and some change is common even in patients without detectable clinical evidence of mental disturbance (Samson et al., 1952). 

Disturbances in the electroencephalogram and in the mental state may be associated with alterations in cerebral blood flow (Scheinberg, 1951). Further evidence suggesting a change in cerebral metabolism is provided by the biochemical studies of Earl et al. (1953). These workers found that the levels of pyruvate in blood, measured 0 and 90 minutes after the administration of 100 g. of glucose, were higher in patients with subacute combined degeneration of the cord than in normal controls. When the test was repeated after two weeks treatment with vitamin B12, normal values were obtained.
