CEBALLOS-BAUMANN‚ M.D.‚ AND GERD PLEWIG‚ M.D.‚ FOR THE HYPERHIDROSIS STUDY GROUP* ABSTRACT Background Treatment of primary focal hyperhidro- sis is often unsatisfactory. Botulinum toxin A can stop excessive sweating by blocking the release of acetylcholine‚ which mediates sympathetic neurotransmission in the sweat glands. Methods We conducted a multicenter trial of botulinum toxin A in 145 patients with axillary hyperhidrosis. The patients had rates of sweat production greater than 50 mg per minute

Nowadays‚ it is one of the common disease causes of mental deterioration in the elderly‚ acetylcholine-releasing neurons‚ which the cell bodies recline in the basal forebrain‚ selectively degenerate developed from compelling evidence.

that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors. The receptors that alcohol binds to are the ones for acetylcholine‚ serotonin‚ gamma aminobutyric acid‚ and glutamate. The two neurotransmitters that distress the behavior effects from alcohol are the gamma aminobutyric acid and glutamate.

"The foundation for much of what we know about sleep was gathered approximately 40 years ago by researcher‚ Michel Jouvet. This French scientist studied the effects of gross brain lesions and brain transections on sleep behavior and related phenomena. It was Jouvet who first suggested that a brainstem region is responsible for the initiation of events that result in the stage of sleep called REM sleep. REM sleep is a stage associated with rapid eye movements‚ a high degree of brain wave activity
