These compounds assist cut back irritation and oxidative stress — a state the place free radicals outnumber antioxidants, resulting in cell harm — two main elements in cognitive decline, says Christina Ni, MD, a board-certified psychiatrist and interventional psychiatry medical director with Mindpath Well being.

The nut additionally accommodates a variety of flavonoids (plant pigments), which act as potent plant compounds that cut back mind irritation, shield towards cell harm, and improve cognitive capabilities like reminiscence and processing velocity, says Ryan Sultan, MD, a double-board-certified psychiatrist and medical director at Integrative Psych of Manhattan.
