Abstract: | A chronic deficiency in central cholinergic function has been implicated in a number of neuropsychiatric disease states. This deficiency most probably exists at the presynaptic nerve terminal in the brain, where acetylcholine metabolism is known to occur. To date there are no reports on animals that could simulate the neurochemical conditions which appear to cause these diseases in humans, as a result of a direct manipulation of the central cholinergic system. Several compounds related to choline have however been studied, which might be useful agents for developing such an animal model, through their specific action on the high-affinity choline transport system in the brain. This minireview presents an overview of results obtained with these potentially neurotoxic choline analogs, and provides a critical analysis of current knowledge in this area of investigation. |
