Overview

The way in which Alzheimer's presents in different people largely depends on the hypothetical construct of "cognitive reserve" – a set of variables including education, intelligence, and mental stimulation which allow the brain to adapt to underlying pathologies. This review suggests that these social and psychological processes are mediated by the noradrenergic system, and that noradrenaline is a protective factor against Alzheimer's.
Schematic role of hypothesized role of noradrenaline in mediating between cognitive reserve and reduced risk of Alzheimer's disease (AD).

Receiving a diagnosis of Alzheimer’s or another form of dementia can be overwhelming. Reframe the diagnosis as an opportunity to form an action-oriented plan for the future. Take a strength-based approach that enriches the lives of families adjusting to a diagnosis of Alzheimer’s.

Gist Distinctions in Healthy Cognitive Aging Versus Mild Alzheimer’s Disease

Memory decline for fine details is often the earliest sign of Alzheimer's disease; however, memory for holistic or global processing (gist) is much more stable throughout the lifetime.
