Samples of brain tissue from those with Alzheimer's revealed marked changes in potassium isotopes that correlated with amyloid-beta accumulation.
Increased potassium currents were responsible for hyperactivity of CA3 neurons. When exposed to potassium channel blockers, the hyperactivity disappeared. However, when exposed to lithium, the drug not only reversed hyperactivity but reduced potassium currents at the same time. The findings strengthen the case that potassium currents play a role in bipolar disorder.
