Alzheimer’s Disease and Dementia

What is Alzheimer’s disease?

Alzheimer’s disease (AD) is an irreversible condition that slowly, progressively destroys brain cells over time. The most common symptoms include loss of memory and thinking skills (otherwise referred to as cognitive impairment). As the disease progresses, people with AD will lose the ability to perform the simplest activities of daily living like dressing themselves, toileting, and bathing.

Every 65 seconds someone in the U.S. develops Alzheimer’s disease. 5.8 million Americans, including 390,000 Texan, are living with AD, and these numbers are expected to increase as the population ages.

Medical Cannabis Uses for Alzheimer’s Symptoms

Alzheimer’s disease symptoms that may respond to cannabis include sleep problems, paranoia, anxiety, dysphoria, pain, poor appetite, and weight loss1. In late stage Alzheimer’s, cannabis may improve appetite, sleep issues, and diminish agitation.

Use of medical cannabis, CBD oil and CBD products, result in anti-inflammatory, antioxidant, and neurogenic effects and clinical studies have reported positive behavioral effects in patients with Alzheimer’s.
