Quizplus · Accepted Answer

Neurofibrillary tangles are abnormal clumps of protein called tau that accumulate inside neurons and disrupt their function. They are a hallmark feature of Alzheimer's disease and other forms of dementia. Telomeres are protective caps on the end of chromosomes that shorten with age, but their association with dementia is still being researched. Free radicals are unstable molecules that can cause damage to cells, but their role in dementia is still being studied. Neurotransmitters are chemical messengers that transmit signals between neurons, but their involvement in dementia is complex and can vary depending on the specific type of dementia.
