Here's a scary thought; the global prevalence (the proportion of individuals that have a specific condition at any given point in time) of Alzheimer's Disease (AD) is expected to quadruple in the next 35 years. That's a lot of people if you consider 5.2 million Americans had AD in 2014. One in nine people over the age of 65 has AD*.
One of the more intriguing concerns with the treatment of AD is how we deal with the psychiatric behavioural problems. And this is not a rare occurence, as behaviour problems are believed to occur in about 70% of individuals with AD.
A newer class of drugs called the atypical antipsychotics are often used to treat behaviour problems such as anger, aggression, or delusions/hallucinations.
