1 Dementia

2 What is Dementia? Dementia is a gradual decline of mental ability that affects your intellectual and social skills to the point where daily life becomes difficult. Dementia can affect your memory and your decision-making ability, can impair your judgment and make you feel disoriented, and it may also affect your personality.

3 Types of Dementia There are many symptoms that lead to dementia but we will cover these 5 types: Alzheimer’s disease Vascular dementia Dementia with Lewy bodies –Lewy Bodies is a combination of Alzheimer's and Parkinson's. Frontal-temporal dementia Creutzfeldt-Jakob Disease

4 Alzheimer’s & Dementia Alzheimer’s is the most common form of Dementia Dementia is not an acute condition that suddenly appears and it usually does not require emergency treatment.

5 Causes of Dementia alcoholism brain injury drug abuse side effects to certain medications In some cases of dementia it may be reversible once the underlying cause has been treated.

6 Aging and a family history of dementia are risk factors for developing dementia. The following factors can also add to the risk of developing dementia: high blood pressure high cholesterol diabetes smoking Unfortunately, when dementia is caused by conditions such as Alzheimer's disease, brain injury, or simply aging (senile dementia), the changes that occur are irreversible.

7 Alzheimer’s Disease See notes that you already have.

8 Vascular Dementia Is commonly referred to as multi infarct dementia. –Infarction is tissue death caused by blockage of the tissue’s blood supply. This type of dementia is the result of brain damage either due to large or small strokes, or to chronically low blood supply to the brain.

9 Vascular Dementia Continued Often, a person with vascular dementia experiences a more sudden loss of memory and function as compared to a person with Alzheimer's disease.

10 Dementia with Lewy Bodies Dementia with Lewy Bodies is one of the more common forms of dementia and can affect as many as one in ten people with dementia. Lewy bodies appear in neurons which are breaking down. When these Lewy bodies are in deep regions of the brain that affect control of movement, this causes Parkinson’s disease.

11 Lewy Bodies continued When compared to Alzheimer’s Lewy Bodies does not follow a progression in steps. Example: In Alzheimer’s, hallucinations generally occur in the later stages. In comparison with Lewy Bodies Dementia, hallucinations can occur at any stage at random, there are symptoms that precede the hallucinations.

12 Frontal Temporal Dementia Affects personality and speech but not memory.

13 Frontal Temporal Dementia How does this one differ from other types of dementia? Unlike most other forms of dementia, memory is not affected in people with this type of dementia until later in the disease. The disease mainly affects different parts of the brain than are affected by other forms of dementia: the frontal and temporal lobes. Also, this form of dementia strikes people at a relatively younger age -- usually between the ages of 40 and 60.

14 Frontal Temporal Disease Sometimes referred to as Picks Disease. These picks (abnormal proteins) disrupt normal brain cell functions. Nearly half of all individuals with Frontal Temporal Disease have family history of the disease.

15 Creutzfeldt-Jakob Disease Creutzfeldt-Jakob Disease (CJD) is a rare, rapid and fatal disease of the central nervous system. Death often occurs within 6-12 months of diagnosis This disease is thought to be caused by Prions, which are particles that change our body's proteins into infectious deadly proteins, which results in brain death.
