Do you know what dementia is? One of the most common misconceptions is that dementia itself is the disease when in fact it is an umbrella term for conditions that affect our brain. From a Mild Cognitive Impairment (MCI) to Alzheimer’s Disease – the term dementia is used to capture those conditions that affect memory, communication, mood, personality and the ability to perform day-to-day activities. Alzheimer’s Disease is one type of dementia, also the most common type of irreversible dementias.
