Alzheimer’s special care units, or SCUs, are the most intensive care options for people suffering from severe memory loss. Some SCUs comprise entire floors of hospitals or nursing homes, or they may stand alone as their own private facilities. These healthcare facilities are built with secured entrances and walkways where patients can walk without getting lost. Outdoor walking and sitting areas are spacious and enclosed. Indoor hallways are often built in circular patters so patients can walk without hitting dead ends, which can cause frustration and sadness in people with dementia. Patients with memory loss receive treatment according to the severity of their conditions. Many patients require assistance with daily activities such as cleaning, cooking and bathing. Others may require counseling or therapy. These facilities provide staff at all hours of the day and night who can respond to the unique needs of their residents.
