Summary

Neurodegeneration refers to the progressive structural and functional loss of neurons. It is the hallmark of diseases including Alzheimer's, Parkinson's, ALS, Huntington's, and frontotemporal dementia. Shared mechanisms across neurodegenerative diseases include proteostasis failure, mitochondrial dysfunction, oxidative stress, synaptic loss, and neuroinflammation. These convergent pathways are key targets for therapeutic intervention.
