Degenerative dementias have been associated with many neurological/neurodegenerative disorders (NDs), most of which are found to be proteinopathies (tauopathy, synucleinopathy, etc.), where aggregates of abnormal proteins, such as amyloid beta-peptides, α-synuclein, tau protein, etc., tend to settle in the brain with the progression of age [5,6]. The gene discussed is SNCA; the disease is tauopathy.
