 Alzheimer's disease (AD) is the foremost cause of dementia, accounting for approximately 60% to 80% of all cases of dementia. This condition is a progressive and neurodegenerative ailment characterized by three principal features within the brain: Amyloid plaques, anomalous clumps formed from proteins, remnants of neurons, and fragments of other nerve cells. Neurofibrillary tangles (NETs), knotted bundles of fibers, containing clusters of a protein known as tau, are situated within neurons. The deterioration of connections between neurons leads to memory and learning deficits. Alzheimer's disease exhibits distinctive brain alterations (pathology) distinct from those of other causes of dementia, such as Lewy body disease or Cerebrovascular disease. When these coexisting pathologies are identified during a person's lifetime, it is called mixed dementia. A common initial clinical symptom includes difficulty recollecting recent conversations, names, or events, accompanied by a...

  Alzheimer's disease (AD) is the most common cause of dementia, accounting for an estimated 60% to 80% of cases. It is a progressive and neurodegenerative disease characterized by three major hallmarks in the brain: Amyloid plaques, which are abnormal clumps made of proteins, remnants of neurons, and bits of other nerve cells. Neurofibrillary tangles (NETs), which are tangled bundles of fibers, including clumps of a protein called tau, are found inside neurons. Loss of connections between neurons is responsible for memory and learning. Alzheimer's disease brain changes (pathology) and the brain changes of one or more other causes of dementia, such as Lewy body disease or Cerebrovascular disease. This is called mixed pathologies, and if recognized during life, it is called mixed dementia. Difficulty remembering recent conversations, names, or events is a common early clinical symptom, as are apathy and depression. Approximately 6.2 million Americans age 65 and older we...
