The cause of early onset Alzheimer’s disease is not known. Through research, there are some risk factors that have been identified as possibly being associated with a diagnosis of early onset Alzheimer’s:
- “Familial Alzheimer’s disease” – scientists have identified several rare genes that directly cause Alzheimer’s. People who inherit these rare genes tend to develop symptoms in their 30s, 40s and 50s.
- Head injuries
- Metabolic syndrome
- Smoking – raises the risk of developing Alzheimer’s disease by as much as 50%
- Type II Diabetes – high blood sugar may cause vascular problems. It is thought that insulin resistance leads to inflammation that can damage the brain by disrupting the proper formation of neuron connections
- Individuals that are overweight or obese in midlife may be at a higher risk
- Down’s Syndrome
