Depression and dementia are both cognitive-impairing diseases that wreak havoc on someone as well as their family. While they are both extremely difficult to handle on their own, they are even worse when combined.

As Next Avenue states, more than 5 million people in the U.S. who have been diagnosed with dementia also suffer from depression. Those with Alzheimer's, a common form of dementia, show symptoms of depression in its earlier stages.

Dementia and depression can be a dangerous mix and it is important for family members and caregivers to seek the help of a physician right away if they feel this is the case for a loved one. According to Dr. Ellen Walker and Dr. David Steffens of Duke University Medical Center, those with both of these diseases may exhibit the following:

Social Withdrawal

Apathy

Irritability

Loss of Appetite

Lethargy

As you can imagine, certain symptoms such as social isolation and not eating may result in the conditions worsening.

While many patients who have dementia may not suffer the full effect of depression, both of these combined must be addressed, especially if the person is older. For more information, check out Next Avenue
