  39. Non-Memory Impairments in AD (and Aging) • Posterior Cortical Processing Systems • Alerting (cortical tonus) • Orienting • Sensory Integration • Inefficient cortical processing in Aging • Corticocortical disconnectivity in AD • Anterior Executive Control Processes • Changes in frontal cortex with age and AD results in less efficient controlled attentional processes • Greater demands placed on anterior executive processes to moderate deterioration in posterior attentional and sensory systems (C) 2011 Thomas F. Collura, Ph.D. &/or E. Festa, Brown University
