Traumatic neurosis from Viet Nam combat or other sources includes many symptoms that can be effectively self-medicated with alcohol, at least initially. These symptoms include chronic anxiety and restlessness, insomnia, and recurrent frightening dreams. Repeated self-medication with alcohol results in tolerance and a need to increase the amount consumed. Attempts to decrease consumption or to abstain can lead to alcohol withdrawal symptoms similar to and exacerbating the initial symptoms of traumatic neurosis. Continuing alcohol use, with the establishment of a vicious circle, can follow. The authors present three case examples. They note that treatment of alcoholism under the conditions described requires specific attention to the underlying traumatic neurosis.

The therapeutic efficacy, utility and safety of bifemelane hydrochloride were studied in 52 elderly depressive patients. The drug was administered as a tablet containing 50 mg orally three times daily for 8 consecutive weeks. The final global improvement rating and global utility rating were respectively 80.8 and 73.1 percent for all patients. The improvement rates on the Hamilton depression rating scale (HAM-D) were more than 60% for depressed mood, guilt, suicide, middle insomnia, delayed insomnia, psychotic anxiety, gastro-intestinal symptom, hypochondriasis, depersonalization and derealization. The rates regarding global symptoms evaluated by the Psychoneurotic rating scale for doctor's use were more than 60% for tension, agitation, irritability and excitement, phobia, depression, hypochondria and nocturnal delirium in psychotic symptoms, and insomnia in addition to palpitation in somatic symptoms. A significant decrease was also observed in the symptoms covered by the Self-rating depression scale of Zung after treatment with this drug. There were no instances of side-effects, nor any abnormalities in laboratory tests, encountered throughout the trial. Therefore, bifemelane hydrochloride is of value for the treatment of geriatric depression.

Alzheimer's disease (AD) primarily results in memory impairment and cognitive deficits in areas such as language, visuospatial function, calculation, praxis and judgement. However, over 30% of patients with dementia develop a group of secondary behavioural disturbances, including depression, hallucinations and delusions, agitation, insomnia and wandering. Because these secondary symptoms impair patients' function, increase their need for supervision, and often influence the decision to institutionalise them, the control of these symptoms is a priority in managing AD. Psychotropic drugs, particularly antipsychotics (neuroleptics), have been a mainstay in treating many of these symptoms, but carry a high risk of adverse effects. Patients with AD may be particularly vulnerable to adverse effects of medications because of changes in pharmacokinetics and neurotransmitter systems, related to both AD and aging. At present, treating secondary symptoms of AD is more of an art than a science. For virtually every group of symptoms, older and newer classes of medications are available, with proven efficacy in patients without dementia and less clear results in AD patients. We review current treatment options and suggest preferences for each symptom complex, based on a trade-off between efficacy and adverse effects. New agents, such as selective serotonin reuptake inhibitors and atypical antipsychotics, may herald the arrival of symptom- (and receptor-) specific drugs with minimal adverse effects.(ABSTRACT TRUNCATED AT 250 WORDS)

Seven hundred twelve patients meeting DSM-III-R criteria for major depression and recommended for antidepressant treatment were treated with moclobemide as outpatients (88%) or inpatients in ordinary psychiatric practices. These differ from the highly selected patients usually studied in antidepressant research, without comorbidity, or coprescription and treated in special clinics. Sixty-five percent were women, with a mean age of 45 (+/- 13.6) years, and 88% were outpatients. Eighty-eight percent had preexisting depression. Eight percent had prior manic episodes. Previous antidepressant treatment for this episode had been received by 69%, with the most common reasons for change to moclobemide being inadequate response (66%) and poor tolerability (20%). The modal final dose was 450 mg. Regarding tolerability, 52% did not report adverse events. The most common adverse events were insomnia or stimulation (13%), nausea (11%), headache or migraine (11%), dizziness or disorientation (6%), sedation or drowsiness (5%), agitation or nervousness (3%), and diarrhea (3%). Only 10% of adverse events were severe, and 83% lasted less than 2 weeks. There was no difference when moclobemide followed fluoxetine use. Most adverse events did not significantly differ from the frequencies reported in double-blind placebo-controlled studies. Concomitant medications from all major drug groups were taken by 520 patients (73%), with no adverse interactions. Moclobemide overdose resulted in an uneventful recovery, whereas mixed overdoses caused no problems other than those attributable to coprescribed medication. On physician clinical global impression, 65% were moderately improved or better after 8 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

In a double-blind, placebo-controlled study, the therapeutic efficacy of two antidepressants with different neurochemical mechanisms of action, amitriptyline and amineptine, was investigated in patients affected by anxious depression. Sixty-six patients with the primary diagnosis of major depression or bipolar affective disorder (DSM-III-R) and meeting additional operational clinical criteria such as anxiety, trepidation, restlessness, early and/or late insomnia, impulsivity, hostility, dysphoria, compulsivity, hyperperspiration, palpitation, pollakiuria and phobias were included. They were randomly assigned to three groups (n = 22) and treated either with placebo, amitriptyline (up to 100 mg/day) or amineptine (up to 200 mg/day) for 6 weeks. Patients showed better response to amitriptyline, a preferential inhibitor of serotonin reuptake, than to amineptine, a selective inhibitor of dopamine reuptake. The present results suggest that alterations in serotonergic rather than dopaminergic transmission contribute to the pathophysiology of anxious depression.

Drug development in psychiatry has evolved from a process dependent on chance discovery to one based on rationally targeting specific mechanisms of action believed to be important in the pathophysiology underlying psychiatric syndromes. Antidepressant pharmacotherapy is the first area to have substantially benefited from this evolution. Serotonin selective reuptake inhibitors (SSRIs) were the first class of psychiatric medications developed based on such molecular targeting. Nefazodone is a new antidepressant that combines blockade of the serotonin-2 receptor with serotonin uptake inhibition. Perhaps as a result of this dual action, nefazodone caused fewer complaints of nervousness (e.g., agitation, anxiety), insomnia, and tremors and a higher incidence of confusion, dizziness, and vision disturbance than do other advanced generation antidepressants based on several different ways of assessing the relative incidence of these adverse effects. Reports of sexual dysfunction on nefazodone and bupropion treatment were lower than on treatment with other recently released antidepressants.

The herbal drug Phytonoxon N (abbreviated as PN) is indicated in nervousness induced insomnia, agitation and/or anxiety. It is composed of alcoholic drug extracts of the plants Corydalis cava (20%) and Eschscholtzia californica (80%). Both plants are rich in isoquinoline alkaloids derived from tyrosine metabolism. Recent research shows that they may influence the neurotransmitter metabolism.

According to the hypothesis implying that the main mechanism underlying opiate addiction is the blockade by opiates of NMDA receptor functions and subsequent upregulation and supersensitivity of the receptors, noncompetitive NMDA receptor blocker dextromethorphan (DM) has been successfully used in the heroin addict treatment. As the stimulation of NMDA receptors modulates the release of neurotransmitters and hormones such as NE, D, ACh, GH, LH, LSH, ACTH etc., all of which have been found responsible for the manifestation of abstinence syndrome signs including craving and neuronal death by excessive stimulation of NMDA receptors, the incomplete blockade of the NMDA receptors minimizes the intensity of the abstinence syndrome and provides the downregulation of the receptors. In the present study, tizanidine (TIZ), which inhibits the release of endogenous excitatory aminoacids by the agonistic activity on alpha 2-adrenoreceptors, was combined with DM to obtain further benefits. Forty-four male and three female heroin addicts were the subjects of the study. Their daily mean heroin intake was about 2.28 g street heroin. The main duration of heroin use was approximately 3.4 years. Two to three hours after abrupt withdrawal, the outpatients were given 15 mg DM every hour, 25 or 50 mg chlorpromazine (CPZ) + 4 mg TIZ every six hours and 10 mg diazepam + 10 mg hyoscine N-butyl Br + 250 mg dipyrone every six hours three hours following CPZ. The addicts were controlled twice a day. Yawning, rhinorrhea, perspiration, piloerection, restlessness, insomnia, emesis, diarrhea, craving, rejection of smoking and pupils were observed and/or questioned. Two of the 47 outpatients took heroin on the first days.(ABSTRACT TRUNCATED AT 250 WORDS)

Questionnaires and clinician rating scales have been used to assess anxious and depressive symptoms among patients with panic disorder, but these methods do not usually evaluate symptoms in the same terms as the standardized criteria of diagnostic interviews. The present study provides data on the prevalence of symptoms of major depressive disorder and generalized anxiety disorder in 64 patients with panic disorder. Symptoms were assessed using DSM-III-R definitional criteria that consider not only the presence and severity of symptoms, but also their duration and pervasiveness. Depressive symptoms that most frequently met definitional criteria for diagnostic significance were fatigue, insomnia, and concentration difficulties. Over 50% of the sample endorsed feelings of tension, irritability, and restlessness. Disturbances in appetite, feelings of worthlessness, and suicidal ideation were found in less than 10% of the nondepressed panic patients. The implications of these findings for conceptualizing the comorbidity among anxiety and depressive disorders are discussed.

Dextromethorphan (DM), the dextrorotatory isomer of 3-hydroxy-N-methylmorphinan, is the main ingredient in a number of widely available, over-the-counter antitussives. Initial studies (Bornstein 1968) showed that it possessed no respiratory suppressant effects and no addiction liability. Subsequently, however, several articles reporting abuse of this drug have appeared in the literature. The drug is known to cause a variety of acute toxic effects, ranging from nausea, restlessness, insomnia, ataxia, slurred speech and nystagmus to mood changes, perceptual alterations, inattention, disorientation and aggressive behavior (Rammer et al 1988; Katona and Watson 1986; Isbell and Fraser 1953; Devlin et al 1985; McCarthy 1971; Dodds and Revai 1967; Degkwitz 1964; Hildebrand et al 1989). There have also been two reported fatalities from DM overdoses (Fleming 1986). However, there are no reports describing the effects of chronic abuse. This report describes a case of cognitive deterioration resulting from prolonged use of DM.
