Abstract: The present invention relates to novel analogs of choline and methods of use or treatment of neurodegenerative disorders and/or conditions such as Parkinson's disease, Huntington disease, Alzheimer's disease and related disorders such as amyotrophic lateral sclerosis, spinal muscular atrophy, Friedrich's ataxia, Pick's disease, Bassen-Kornzweig syndrome, Refsom's disease, retinal degeneration, Cruetzfelt-Jacob syndrome or prion disease (mad cow disease), dementia with Lewy bodies, schizophrenia, paraneoplastic cerebellar degeneration and neurodegenerative conditions caused by stroke. The present compounds are effective to treat any neurological condition where acetylcholine transmission neurons and their target cells are affected.
