Depression in Alzheimer's disease can be different too

People with Alzheimer's may experience depression differently from that of people without Alzheimer's. For example, individuals diagnosed with Alzheimer's disease:

• May have symptoms of depression that are less severe
• May experience episodes of depression that don't last as long or come back as frequently
• Seem less likely to talk of suicide and attempt suicide less often

Scientists aren't sure of the exact relationship between Alzheimer's disease and depression. The biological changes caused by Alzheimer's may intensify a predisposition to depression.

On the other hand, depression may increase the chances of developing Alzheimer's disease.

It's clear that depression has a strong effect on quality of life for people with Alzheimer's disease. Depression can lead to:

• Worsening cognitive decline
• Greater disability involving daily living skills
• Increased dependence on caregivers
