A range of neurological disorders, including epilepsy and dystonia, may involve dysfunctional intracortical inhibition, and may respond to treatments that modify it. Parkinson’s is a neurodegenerative disease characterized by increased activity of GABA in basal ganglia and the loss of dopamine in nigrostriatum, associated with rigidity, resting tremor, gait with accelerating steps, and fixed inexpressive face. Neurological deficits, along with neuromuscular involvement, are characteristic of mitochondrial disease, and these symptoms can have a dramatic impact on patient quality of life. Neurological features may be manifold, ranging from neural deafness, ataxia, peripheral neuropathy, migraine, seizures, stroke‐like episodes and dementia and depend on the part of the nervous system affected.

    Amyloid 17-42 155178-13-5 98%
    Amyloid 17-42 (Aβ(17-42)) is a major constituent of diffuse plaques in Alzheimer's disease and cerebellar pre-amyloid in Down's syndrome, derived by alpha- and gamma-secretase cleavage of the amyloid precursor protein (APP). Amyloid 17-42 can induce neuronal apoptosis via a Fas-like/caspase-8 activation pathway.
