Lewy body dementia
Resources for Patients and Caregivers
Lewy body dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood.
Wiki Number: 26-Lewy Bodies Disorder/Dementia
US Patients: American actor and comedian Robin Williams committed suicide in 2014 with Parkinson’s and Lewy Bodies.
Age Onset: after age 50 with life expectancy of 8 years after diagnosis
Brain Area: The SNCA gene encodes the alpha-synuclein protein which is a building-block of Lewy bodies.
Symptoms: acting out dreams, visual hallucinations, attention difficulties, slowness of movements
Progression: dementia and Parkinson’s patients may also be affected. Cause cognitive fluctuations.
Causes: clumps of protein form on brain neurons causing heart and digestive functions, low blood pressure and apathy.
Therapies: Cognitive training, deep-brain and transcranial direct current stimulations have been used.

- The role of the endolysosomal pathway in α-synuclein pathogenesis in Parkinson's diseaseby Jessica K Smith on January 27, 2023
Parkinson's disease (PD) is a chronic neurodegenerative disease that is characterized by a loss of dopaminergic neurons in the substantia nigra pars compacta of the midbrain (SNpc). Extensive studies into genetic and cellular models of PD implicate protein trafficking as a prominent contributor to the death of these dopaminergic neurons. Considerable evidence also suggests the involvement of α-synuclein as a central component of the characteristic cell death in PD and it is a major structural...
- A case of exploding head syndrome preceding the onset of mild cognitive impairment with Lewy bodiesby Shogo Kitagawa on January 27, 2023
- Exosomes for the diagnosis and treatment of dementiaby Hyeon Su Joo on January 27, 2023
PURPOSE OF REVIEW: Dementia is a syndrome with several possible pathologies. To date, definitive methods for diagnosis and treatment of sub-types of dementia have not been established. Emerging evidence suggests that exosomes can provide important information for the diagnosis and treatment of several subtypes of dementia. This article reviews recent studies on the application of exosomes in dementia.
- Bradykinesia in Neurodegenerative Disorders: A Blinded Video Analysis of Pathology-Proven Casesby Luca Marsili on January 27, 2023
