In any relationship, problems can arise when one person wants to have sex and the other completely unable to understand it. A very pathetic situation of this kind arises when Alzheimer’s involve in it. Memories define and design an individual. The reminiscence of the happenings, which flows through the course of life, gets preserved in a cryptic way. The entire different medical practices so far human race devised and developed, place human brain as an epitome of this activity. Alzheimer disease is nothing but degeneration of brain and there by losing memories. 

As brain is responsible for behavior and emotion, the brain is in charge of sexual feelings. Alzheimer’s causes unpredictable changes in sexuality. Depending on which part of the brain have been damaged; people with Alzheimer’s experience either more interest in sex or less interest. Alzheimer’s have got complete impact in every aspect of sexual life. A person who diagnosed with the disease will have more or less ability to perform sexually, changes in sexual manners (for example, appearing less sensitive to the other person's needs or appearing sexually aggressive), changes in levels of inhibitions (the person may do or say things that they would not have done previously), and more or less ability toperform sexually.

Majority of people with Alzheimer’s are 65 and older. But Alzheimer's is not just a disease of old age. Up to 5% of people with the disease have early onset Alzheimer's (also known as younger-onset), which often appears when someone is in their 40s or 50s. Alzheimer’s effect on sexual performance and interest becomes a real frustration for the partners of the onset Alzheimer’s affected as they are still young and have burning desires and strong sexual urge. Most of us treat Alzheimer’s as a mental condition. It has got both mental and physical impacts. Research studies coming out from diverse sources in medical field says that, understanding it and supporting the affected with compassionand patience is very important.
