Unlocking Neuroprotection: Potassium Channel Openers in Alzheimer's Disease

Alzheimer's disease is a neurodegenerative disorder characterized by impairments in cognitive functions such as thinking, behavior, and memory. The major pathological abnormalities associated with the disease include the formation of neurofibrillary tangles and amyloid plaques, which further cause neuroinflammation and nerve cell death. Currently, treatments for the disease focus on symptomatic management rather than addressing the root cause of neurological changes. Therefore, the current status of therapy highlights the need for more effective therapeutic substances that can either prevent abnormal deposition or slow neurodegeneration to preserve nerve cells. In this respect, ATP-sensitive potassium channel openers may have a potential role in prevention and protection. The present article focuses on several cellular mechanisms of this class, including the limitation of neuronal excitability, modulation of neurotransmitter release, prevention of aberrant protein buildup, reduction of excessive calcium influx, reduction of reactive oxygen species levels, and reduction of microglial activation.
