Neurophysiology And Neurosurgeries

Alzheimer's disease and dementia are characterized by neurophysiological changes, primarily involving the accumulation of amyloid-beta plaques and tau tangles, which disrupt neural communication. These pathological alterations lead to the degeneration of neurons, particularly in the hippocampus and cortex, affecting memory and cognitive functions. Neuroinflammation and synaptic loss further exacerbate the condition, impairing neural circuitry.

In advanced stages, neurosurgeries such as deep brain stimulation (DBS) are being explored as potential treatments. DBS involves implanting electrodes in specific brain regions to modulate neural activity, aiming to alleviate symptoms and improve cognitive function. While still experimental, these interventions offer hope for managing severe cases, highlighting the intricate interplay between neurophysiological mechanisms and surgical innovations in addressing Alzheimer's and dementia.
