BACKGROUND Previous research in younger individuals has shown that acetylcholinesterase inhibitors tend to enhance REM sleep. METHODS Forty-two healthy elderly persons participated in a double-blind placebo-controlled polysomnographic study (parallel group design). RESULTS The present study indicates that in the elderly persons, donepezil, an acetylcholinesterase inhibitor also exerts a marked effect on REM sleep parameters: REM density was increased whereas REM latency was reduced, thus, confirming the findings of our pilot study described earlier. CONCLUSIONS Whether the cholinergic stimulation measured by polysomnography is related to treatment efficacy is a very interesting but an open question. Based on the findings that REM sleep is associated with memory consolidation, the question whether REM sleep augmentation enhances memory performance-as suggested by the findings of the pilot study-seems to be an interesting topic for future research.

D010275 Parasympathetic Nervous System The craniosacral division of the autonomic nervous system. The cell bodies of the parasympathetic preganglionic fibers are in brain stem nuclei and in the sacral spinal cord. They synapse in cranial autonomic ganglia or in terminal ganglia near target organs. The parasympathetic nervous system generally acts to conserve resources and restore homeostasis, often with effects reciprocal to the sympathetic nervous system.

D002800 Cholinesterase Inhibitors Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.
