Alzheimer’s disease is a disease that causes the function of brain cells to deteriorate. The patient’s ability to think and complete daily duties has deteriorated. Increased age, with an average age of 80 years, genetic variables, head injuries, vascular disease, and environmental factors are all risk factors. There is no cure for this condition, which is progressive. Symptoms can be treated with drugs like cholinesterase enzyme inhibitors and N-methyl D-aspartate (NMDA) antagonists. (Breijyeh & Karaman, 2020)

Frontotemporal dementia (FTD) is a form of dementia that affects the frontal and temporal lobes of the brain. As the nerve cells deteriorate, the result is behavioral changes in the individual prior to memory deficits. Family history is currently thought to be the only known risk factor for FTD. There is no specific drug to combat FTD. The patient is given drugs that will stabilize behavior. (Alzheimer’s Association, 2022)

The patient has been getting lost in the neighborhood and that has resulted in the neighbors returning him home. He is reported to get agitated when asked about his behavior. He is exhibiting unsafe behavior such as inviting strangers into the home as well as the inability to complete activities of daily living. The patient has a family history of Alzheimer with his father dying at age 78 from the disease.

A buildup of beta-amyloid is the cause of the Amyloid hypothesis. This amyloid cell buildup is regarded to be the first sign of a possible dementia diagnosis. Neuron cells die because of this complicated process. Dementia is caused by a reduction of neurological brain cells. (Ricciarelli, R., and Fedele, E., 2017)

As stated in the assessment the patient is exhibiting moderate dementia related to the MMSE score. The patient’s behavior supports this assessment. The patient is wandering through his once familiar neighborhood, he has difficulty dressing himself and behavioral changes.
