As you can see there are differences between the symptoms of depression and of Alzheimer’s disease and mainly the differences are related to memory. While there can be mood changes associated with the symptoms of Alzheimer’s disease, this type of dementia is more of a cognitive disorder rather than a mood disorder like depression. Memory problems can also be associated with depression however so remember only a medical professional like your doctor can correctly diagnose your symptoms.

Risk Factors for Depression

Some people are more likely to experience depression. According to the National Alliance on Mental Illness, “Older women are at a greater risk because women in general are twice as likely as men to become seriously depressed. Biological factors like hormonal changes may make older women more vulnerable. The stresses of maintaining relationships or caring for an ill loved one and children also typically fall more heavily on women, which could contribute to higher rates of depression. Unmarried and widowed individuals as well as those who lack supportive social network also have elevated rates of depression. Conditions such as heart attack, stroke, hip fracture or macular degeneration and procedures such as bypass surgery are known to be associated with the development of depression.”

Risk Factors for Dementia Diseases like Alzheimer’s Disease

According to the Alzheimer Society of BC some people have increased risk of being diagnosed with Alzheimer’s disease. There are some risk factors that one cannot control like age, gender and genetics and there are risk factors one does have some control over. In terms of age, “In Canada, 1 in 20 people over the age of 65 is affected by Alzheimer’s Disease. For people over 85 years, the likelyhood of having dementia increases to approximately 1 in 4 people.” (Alzheimer Society BC, 2013). Women are more likely to be diagnosed with Alzheimer’s disease and if it runs in your family you are even more at risk.

There are risk factors that can be controlled and they include having diabetes, heart problems, and brain injuries. Keeping your body as healthy as possible will reduce the risk of Alzheimer’s disease. If you or your loved one is experiencing some of the above symptoms of either depression or Alzheimer’s disease, please see your doctor.
