Synucleinopathies

Synucleinopathies encompass a group of neurodegenerative disorders characterized by abnormal accumulation of alpha-synuclein protein aggregates in the brain. While commonly associated with Parkinson’s disease, recent research has implicated synucleinopathies in Alzheimer’s disease and other dementias. In Alzheimer’s, alpha-synuclein aggregates have been found to co-exist with tau and beta-amyloid plaques, hallmark proteins of Alzheimer's pathology. This co-occurrence suggests a potential overlap in disease mechanisms or synergistic pathological effects. The presence of alpha-synuclein pathology in Alzheimer’s patients often correlates with more severe cognitive impairment and faster disease progression. Understanding the role of synucleinopathies in Alzheimer’s and dementia could lead to novel diagnostic markers and therapeutic strategies targeting multiple pathological pathways, offering hope for more effective treatments in the future.
