Behavioral and Physiological Effects of Visual Training

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to evaluate the learnability of a 3 week, 40 minutes per day, 5 day per week, computer-based visual training exercise by healthy mature individuals undergoing normal aging.

Detailed Description
-----------------
Virtually all adults will suffer a decline in their cognitive capacities to some degree. Typically, cognitive decline is characterized by a slow, progressive decline in abilities (frequently in memory, attention, inhibition and speed of processing) relative to younger adults, commonly called normal aging, age-associated memory impairment, age-consistent memory impairment, benign senescent forgetfulness, late-life forgetfulness, ageing-associated cognitive decline, and the preferred term, age-related cognitive decline (ARCD) As virtually all adults experience a reduction in their cognitive abilities with age, ARCD has generally been considered to be a normal, inevitable, and irreversible part of aging; and the extremely severe forms of pathological cognitive decline (e.g., Alzheimer's disease, AD) have dominated therapeutic research in this area. However, ARCD represents an important cause of quality of life decline in almost every older adult, as the impact of forgetfulness and mental slowing increasingly change the abilities of individuals to successfully manage their day-to-day activities. Therapeutic approaches targeting the specific problems of ARCD in normal aging (as opposed to the pathological problems of AD) would unto themselves represent important clinical advances. This trial investigates the effects of a computer-based visual training exercise built on the principles of positive brain plasticity and designed for use by healthy mature individuals. The program is specifically designed to improve the fidelity of sensory representations in early visual cortex.
