128 case reports of drug-induced mania were reviewed. Steroids, levodopa and other dopaminergic agents, iproniazid, sympathomimetic amines, triazolobenzodiazepines and hallucinogens were the agents that most commonly induced manic syndromes. The most common characteristics of drug-induced manic episodes were increased activity, rapid speech, elevated mood, and insomnia. Patients who developed mania often had a prior history, family history, or current symptoms of mood disturbance. The episodes were most commonly treated by discontinuing or reducing the dose of causative agent. Discontinuation of the inciting drug and treatment with neuroleptic agents were equally efficacious: lithium treatment was less effective. The majority of agents that induce mania have an effect on monoaminergic systems.

The antagonism of melatonin in models of Parkinson's disease (PD) can reduce the severity of motor impairment associated with dopamine (DA) degeneration. In consideration of the potent antidepressant effects of bright light therapy (LT), that LT suppresses melatonin secretion, that depression is commonly observed in PD, and that exposure to constant light facilitates recovery from experimental PD, the object of the present study was to strategically administer LT to PD patients and observe the effects on depression, insomnia, and motor performance. Twelve patients diagnosed with PD were exposed to white fluorescent light for 1-1.5 h at an intensity of 1000 to 1500 lux once daily commencing 1 h prior to the usual time of sleep onset, approximately 22:00 h in most patients. All patients were assessed before LT commenced and at two weeks, five weeks, and regular intervals thereafter. Within two weeks after commencing LT, marked improvement in bradykinaesia and rigidity was observed in most patients. Tremor was not affected by LT treatment; however, agitation, dyskinaesia, and psychiatric side effects were reduced, as verified by decreased requirement for DA replacement therapy. Elevated mood, improved sleep, decreased seborrhea, reduced impotence, and increased appetite were observed after LT. LT permitted the reduction of the dose of L-dopa, bromocriptine, or deprenyl in some patients by up to 50% without loss of symptom control. Factors limiting the efficacy of LT included multiple disease states, treatment compliance, polypharmacy, emotional stress, advanced age, and predominance of positive symptoms. The results of this case series study confirms previous work describing light as efficacious in the treatment of PD and suggest that controlled trials may help to elucidate how LT might be used strategically as an adjunct therapy to improve the morbidity of PD patients.

Mania is a mood disorder characteristic of certain psychiatric conditions and is exhibited by high energy, elevated mood, irritability, insomnia, and pressured speech. Though commonly attributed to bipolar and schizoaffective disorders, mania may be precipitated by other non-psychiatric conditions, including substance abuse, medications, metabolic disturbance, and organic brain pathology. Steroid-induced mania is not uncommon and may present with a number of psychiatric symptoms. Brain tumors presenting with predominantly psychiatric symptoms are a relatively uncommon cause of mania and may persist or recede with treatment. A case of mania in a cancer patient with brain metastasis and steroid use, with no prior history of mania, is discussed herein.
