Is Dementia Hereditary?
Dementia refers to a group of neurodegenerative conditions marked by cognitive decline, memory loss, and impaired reasoning. Alzheimer's disease is the most common form, with other types including vascular dementia, Lewy body dementia, and frontotemporal dementia. Globally, about 55 million people live with dementia, a figure projected to increase to 78 million by 2030. As dementia affects millions, many wonder whether it is hereditary.
