Brain Neuroplasticity & Receptor Recovery Timeline

Months 1 to 3:

Acute withdrawal stabilization; initial normalization of basal dopamine transporters in the nucleus accumbens.

Months 6 to 9:

Significant restoration of prefrontal cortex executive cognitive control and impulse decision-making circuits.

Months 12 to 14+:

PET brain scan studies demonstrate near-complete recovery of striatal dopamine D2 receptor availability.
