[Deanol in tardive dyskinesia: a double-blind study (author's transl)].

Tardive dyskinesia following long-term application of neuroleptics is resistant to treatment. According to the hypothesis of a relative central nervous system acetylcholine lack as the underlying mechanism 20 patients were treated with dimethylaminoethanol (Deanol) in a double-blind study. Deanol is known to be a direct precursor of intracerebral acetylcholine. For several reasons (which are discussed) the data of but 11 patients were statistically evaluated. The results suggest some therapeutic effect in some of the patients only (significant improvement of oral hyperkinesia).

Mood alterations during deanol therapy.

An imbalance between central cholinergic and adrenergic influences may affect mood disorders. Of 38 patients taking high doses of deanol, a putative acetylcholine precursor, eight developed changes in mood: five became depressed and three became hypomanic. A predisposition is suggested as seven of these eight patients had histories of affective symptoms. There was no relationship between the changes in dyskinesias and mood. These observations have both practical and heuristic implications for the management of patients and for further research into the pharmacology of affective disorders and deanol.

The effects of deanol on cognitive performance and electrophysiology in elderly humans.

Deanol (900 mg/day for 21 days) had no effect on learning a list of words when tested at weekly intervals. Tests of simple and complex reaction time and a test of continuous serial decoding of digits showed no enhancement with the drug. Several components of evoked potentials recorded from several scalp sites did show enhanced amplitude under drug treatment. These changes were not accompanied by changes in the EEG spectrum as are seen with some other psychoactive drugs. Deanol seems to be an ineffective treatment for the normal slowing of cognitive function seen in the normal elderly person or those elderly with only minimal cognitive decline and free of symptoms of dementia. Contrary to earlier reports, elderly persons were found to be able to benefit from warning signals in a complex reaction time task.

Treatment of phenothiazine induced bulbar persistent dyskinesia with deanol acetamidobenzoate.

The late manifestation of neuroleptic-induced dyskinesia (persistent dyskinesia) is an irreversible complication of long-term treatment that is poorly understood and difficult to treat. Recently, a theory of dopamine receptor hypersensitivity in the dopaminergic-cholinergic system has suggested an explanation of choreiform movements and, thus, an implication for the management of persistent dyskinesia. The case presented is that of bulbar persistent dyskinesia in a patient who had been prescribed a phenothiazine derivative for eleven years; his symptoms improved with the use of deanol, which probably converts to acetylcholine after crossing the blood brain barrier. This improvement suggests that deanol may shift the neuroleptic-induced dopaminergic-cholinergic system unbalance toward equilibrium by matching predominant dopaminergic effect or by enhancing deficient cholinergic action in the dopaminergic-cholinergic system. This isolated finding needs to be confirmed by more research in neuropharmacology.

Double-blind evaluation of deanol in tardive dyskinesia.

We administered deanol acetamidobenzoate, 2.0 g/day for four weeks, a double-blind, placebo-controlled crossover trial, to 14 patients with tardive dyskineasia. The patient population included both inpatients and outpatients. The response was evaluated by subjective clinical impression and scoring of filmed sequences. Patients' conditions improved significantly from baseline scores while receiving both deanol and placebo, but there was no distinction between the two treatments.

Deanol in minimal brain dysfunction.

The literature on minimal brain dysfunction is confused, confusing and controversial. The statements that the condition exists, needs treatment, and that treatment may be pharmacological, are more expressions of faith than accepted fact. We believe they are true (within limits not discussed in the article). Furthermore, there is evidence that some patients with MBD are hypo-aroused, while others are not. The role of deanol in the treatment of MBD is still unclear, because of the complexities of identifying appropriate patients in terms of levels of arousal, as well as identifying appropriate measures of response. There is sufficient support for an effect of deanol in the literature to justify further investigation. Further studies should attend to important methodological problems as discussed.

Split face study on the cutaneous tensile effect of 2-dimethylaminoethanol (deanol) gel.

BACKGROUND/AIMS: Beyond subjective assessments, the effect of skin tensors is difficult to assess. The present 2-phase randomized double-blind split face study was designed to compare the effect of a gel containing 3% 2-dimethylaminoethanol (deanol, DMAE) with the same formulation without DMAE. METHODS: In a first pilot study, sensorial assessments and measures of the skin distension under suction were performed in eight volunteers. In a second study conducted in 30 volunteers, shear wave propagation was measured. RESULTS: Large interindividual variations precluded any significant finding in the first study. The DMAE formulation showed, however, a significant effect characterized by increased shear wave velocity in the direction where the mechanical anisotropy of skin showed looseness. CONCLUSION: The DMAE formulation under investigation increased skin firmness.

2-dimethylaminoethanol (Deanol) in Huntington's chorea.

A double-blind crossover trial with 2-dimethylaminoethanol (Deanol), a possible precursor of brain acetylcholine, was carried out in nine patients with Huntington's chorea. It was found to be ineffective in inducing any alteration in hyperkinesia.

Orofacial and respiratory tardive dyskinesia: potential side effects of 2-dimethylaminoethanol (deanol)?

A case of essential tremor since early adultness is presented, which has been treated successfully with the acetylcholine precursor 2-dimethylaminoethanol (deanol) for 10 years. Development of a marked dyskinesia syndrome affecting predominantly orofacial and respiratory musculature has been noticed with this medication. Partial remission after discontinuation and a favorable response to anticholinergics are suggestive of an adverse drug effect.

Deanol in the treatment of tardive dyskinesia.

A patient who developed severe tardive dyskinesia after the termination of long-term phenothiazine therapy was successfully treated with deanol, a possible precursor of acetylcholine. Physiological measurements were obtained to quantify the clinical course. The authors discuss the practical and heuristic implications of these observations and suggest further consideration of therapy directed toward enhancement of cholinergic activity in the central nervous system.

Dimethylaminoethanol (deanol): effect on apomorphine-induced stereotypy and an animal model of tardive dyskinesia.

Dimethylaminoethanol (DMAE) was administered acutely to rats subsequently injected with spomorphine. A dose of 80 mg of DMAE had no effect on the severity of apomorphine-induced stereotypy. However, 160 mg of DMAE significantly diminished the severity of apomorphine-induced stereotypy. This dose of DMAE did not significantly alter spontaneous locomotor activity. DMAE did not reduced apomorphine-induced stereotypy in animals previously exposed to haloperidol and presumed to have postsynaptic dopamine receptor supersensitivity. These results with DMAE are contrasted with the effects of choline chloride, and suggest that choline chloride may be more effective than DMAE at augmenting striatal cholinergic activity.
