1. The authors review the literature describing acute symptomatology produced by the gradual or abrupt withdrawal of heterocyclic antidepressants, monoamine oxidase inhibitors (MAOI) and neuroleptics. 2. Withdrawal of heterocyclic antidepressants and antipsychotic agents causes similar symptomatology. Symptoms produced by the discontinuation of these drugs include nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. 3. Psychotic relapse is often presaged by anxiety, agitation, restlessness, and insomnia. Prodromal symptoms are distinguished from the effects of neuroleptic withdrawal by a temporal relationship of the latter to reductions in the dosage or discontinuation of antipsychotic agents. 4. Withdrawal of MAOIs can result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, delirium, and paranoid psychosis. 5. MAOI withdrawal phenomena resemble the symptoms produced by the discontinuation of chronically administered psychostimulants. 6. The capacity of MAOIs to exert amphetamine-like effects presynaptically and the propensity of somatic treatments for depression to subsensitize presynaptic receptors regulating the release of catecholamines provide a basis for the development of psychotic symptoms upon the withdrawal of MAOI. Evidence for this hypothesis is reviewed.

Effectiveness of alprazolam in daily dosages of 0.8-1.2 mg was studied in 28 patients who showed psychotic symptoms or autonomic imbalance symptoms after operation for breast cancer. Psychotic symptoms included depression, anxiety, tension, and restlessness, and symptoms of autonomic imbalance included sleep disorder, anorexia, and pains. All of these symptoms were improved at high ratios by alprazolam. The drug was very useful in 16 cases (57.1%), useful in 11 cases (39.3%), and slightly useful in one case (3.6%). The only adverse reaction reported was unsteady gait in one case.

According to the hypothesis that the development of physical dependence on and tolerance to opiates depends on the inhibition by opiates of L-asparaginase and L-glutaminase activities in the brain, and the blockade by opiates of the aspartatergic/glutamatergic receptors especially NMDA, four female and fourty-four male heroin addicts were included in a double-blind clinical trial. Four mg chlorpromazine (CPZ) was administered every hour and 10 mg diazepam (DIA) every 6 hours to a group consisting of two female and nineteen male inpatients. The remaining subjects received 15 mg non-opioid antitussive dextromethorphan (DM) instead of CPZ. The withdrawn addicts were controlled twice a day and yawning, lacrimation, rhinorrhoea, perspiration, goose flesh, muscle tremor, dilated pupils, anorexia, joint and muscle aches, restlessness, insomnia, emesis, diarrhea, craving and rejection of smoking as abstinence syndrome signs were observed and rated on a scale of 1, 2 and 3 points according to their intensity. All signs, except perspiration and emesis, were significantly less intense in the group given DM + DIA than CPZ + DIA. The other plus points included the immediate stop of craving and the early onset of smoking in DM + DIA group. The results are considered to be supporting evidence for the hypothesis emphasizing the blockade of NMDA receptors by opiates in opiate addiction. Furthermore, the decrease caused by non-opioid NMDA antagonists in the responsiveness of NMDA receptors appears very promising for the treatment of opiate addicts.

Buxaminol-E injected i.v. to conscious cats evoked hypothermia, tachypnoe, anorexia, salivation, defecation, decrease of spontaneous activity and sensitivity to painful stimulus and agitation during its administration. The above mentioned effects of B--E, with the exception of the antinociceptive action which was not examined and of the initial excitation, were observed also after intracerebroventricular (i.c.v.) administration of B--E, and they were depressed by atropine administered i.c.v. Our findings suggest a central cholinergic action of B--E in conscious cats. Paroxysmal tonic-clonic convulsions and circling observed only after i.c.v. administration of B--E and piloerection, ataxia and urination were not inhibited by atropine administered i.c.v.

One hundred and thirty out-patients with depression were studied by grade of membership multivariate (GOM) analysis. Five depressive types were generated. Pure Type I represented a mild form of melancholia in older, stable males, who showed a modest drug response. Pure Type II included obsessive-anxious symptoms in older patients who responded well to an MAOI drug, but poorly to placebo. Pure Type III was a mildly symptomatic form of depression which responded well to placebo. Pure Type IV included features of agitation, mood worsening later in the day, anorexia and depersonalization; it was commonly precipitated by external stress and MAOI treatment was more effective than placebo. In Pure Type V depression, patients were mostly younger females with high levels of symptomatology, atypical vegetative symptoms, unstable life-styles, disadvantaged backgrounds and a poor response to MAOI and placebo. These results resemble in many ways our earlier GOM study of depression, as well as other multivariate studies of depression in the literature.

Teething does not appear to cause diarrhea, fever, rashes, seizures or bronchitis. It may be associated with some daytime restlessness, thumb sucking, gum rubbing, drooling and temporary loss of appetite. It is not clear whether these signs are developmental in origin or are actually related to tooth eruption. Illness occurring with teething should be thoroughly evaluated so that a serious systemic disturbance is not overlooked.

The authors review the literature discribing non-dyskinetic antipsychotic withdrawal phenomena. Withdrawal of these agents can cause nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgia, paresthesia, anxiety, agitation, restlessness, and insomnia. Psychotic relapse is often presaged by increased anxiety, agitation, restlessness and insomnia, but the temporal relationship of these prodromal symptoms to reduction in the dosage or discontinuation of neuroleptics distinguishes them from the effects of abrupt withdrawal.

The literature describing nondyskinetic antipsychotic withdrawal symptoms is reviewed. The withdrawal of antipsychotic agents can result in nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. Psychotic relapse is often presaged by increased anxiety, agitation, restlessness, and insomnia. However, the temporal relationship of these prodromal symptoms to reduction in the dosage or discontinuation of neuroleptics distinguishes them from the effects of abrupt withdrawal.

The psychopharmacological effects of fluvoxamine, 50 mg twice a day, were compared with those of mianserin, 20 mg twice a day, and placebo, each given for 8 days in a double-blind crossover design to 9 healthy human volunteers. At least one week was left between the 8-day courses of drugs. Testing was carried out before and 3 h after taking the morning dose on Days 1 (pre-drug), 4, and 8, and comprised EEG, cognitive and psychomotor tasks, and self-ratings of mood and bodily symptoms. Fluvoxamine had no effect on any of the EEG wavebands, but mianserin increased voltages in the slow wavebands as compared with placebo. This effect was particularly pronounced on Days 4 and 8. Mianserin significantly decreased critical flicker fusion frequency and speed of reaction time, and slowed down tapping rate; digit symbol substitution and symbol copying test performances were also impaired by mianserin. These effects were most marked after the first dose and had lessened somewhat later in the week. Symbol copying was the only task impaired by fluvoxamine as compared with placebo. Mianserin caused drowsiness after the first dose but this effect declined by Day 8. By contrast, fluvoxamine induced feelings of anxiety, sweatiness, trembling, nausea, loss of appetite, restlessness, muscle tension, irritability, tiredness, headache, and dizziness; these effects were most evident in the middle of the week and relatively reduced at the end of the week. Mianserin produced a few of these effects but they tended to be maximal on Day 1 or 4 and then to wear off.(ABSTRACT TRUNCATED AT 250 WORDS)

Masked depression refers to a concept of a phenomenological state, either endogenous or psychogenic where somatic symptoms replace sadness: Thirty patients were evaluated by RDC (22 endogenous and 8 masked depressions) wherein in the latter dysphoria was replaced by a nonreactive persistent somatic complaint. They were rated on Beck and Hamilton Depression Scales, on Hamilton and Trait-State Anxiety Scales and the NOSIE. All patients presented with insomnia, anorexia, loss of weight, diminished libido and anhedonia. Initial ratings were similar for both diagnostic groups except for a significantly higher agitation factor and lower retardation in masked depression. Although 59.9 percent of the subjects are positive on the dexamethasone test, only 1 masked depression did not suppress secretion of cortisol. After a randomized 30-day drug trial where patients were assigned to Clomipramine or Desipramine, patients in both groups show significant improvement on rating scales but diagnostic group drug treatment interaction exists on anxiety and agitation criteria.
