Evidence Snippets
Scientists are gradually moving away from the simple assumption, as proposed in the original amyloid hypothesis, to new theories of pathogenesis, including gamma oscillations, prion transmission, cerebral vasoconstriction, growth hormone secretagogue receptor 1α (GHSR1α)-mediated mechanism, and infection.
Activity in the theta, beta, and gamma bands is related to communication between PFC and different brain areas.

Linked Claims
Abnormal gamma oscillations have been linked to Alzheimer's disease, Parkinson's disease, and schizophrenia.
Gamma oscillations control connectivity between different brain regions and are important for perception, movement, memory, and emotion.
Brain inflammation, oxidative stress, and metabolic imbalances can disrupt the interneuron network required for gamma oscillations.
Inhibitory interneuron networks are necessary for the production of gamma oscillations.
The review states that Alzheimer's disease pathogenesis research is moving beyond the original amyloid hypothesis toward additional mechanisms including gamma oscillations, prion transmission, cerebral vasoconstriction, GHSR1α-mediated mechanisms, and infection.
