Many neurodegenerative conditions are associated with the accumulation of forms of metabolic waste in the central nervous system, protein aggregates that form solid deposits between or within cells. Tauopathies such as frontotemporal dementia are associated with tau aggregates, synucleinopathies such as Parkinson’s disease with α-synuclein, and amyloidoses with varying forms of amyloid, such as the amyloid-β found in elevated amounts in Alzheimer’s disease patients. Alzheimer’s itself is an amyloidosis that also becomes a tauopathy in its later stages. These protein aggregates and their surrounding halos of harmful biochemistry disrupt normal brain function and, in the worse cases, kill neurons. Eventually they kill the patient. With the exception of certain inherited conditions, in which cellular biochemistry is broken due to an unfortunate and unlucky mutation, why
