Since time immemorial, numerous medical conditions affecting humans have been discovered and researched on. Yet still, more appear every day. All medical conditions are grouped into two, depending on their characteristics and way of infection. The first group consists of Communicable diseases. Just like in communication, agents of these diseases are passed through sharing of body fluids, personal items and through respiratory gases. On the other hand, Non-Communicable diseases are not shared or spread. They are acquired through bad diets and lifestyle choices. Individuals with genetics or family history of such diseases, make them more susceptible. Dementia is a word borrowed from Latin. It means madness of the mind. Dementia is a Non-communicable condition. Mostly associated with the aged from 65 years, it involves loss of memory gradually with time. Early Onset Dementia occurs to people below the age of 65 years. In this case, head injury is the main culprit behind it. If it affects children, it is known as Juvenile Dementia. This occurs when the child is suffering from a severe medical condition like Meningitis, which in turn affects brain cells. Dementia is a condition that represents a group of conditions which affect the brain’s functions that are behind speech, attention, memory, visual perception and problem solving capabilities. Patients often struggle to remember appointments, handle short term memory and run simple errands. Dementia cases are mostly progressive. They start out simple in the form of memory lapses, but advance slowly and gradually. No cause for alarm if symptoms like memory lapses start to appear, as they may just is caused by other factors. However, a visit to the doctor should be planned to ensure correct diagnosis is done. Damage of the brain cells, mainly due to ageing, is the main cause of Dementia. Damage interferes with brain cell communication thus inhibiting brain activity. The situation becomes worse if the affect brain cells are behind certain brain functions. Emotional instability and stress during social situations are some of the behavioural characteristics of Dementia patients. Doctors are yet to come up with a standard test for Dementia. Tests include physical examination, laboratory tests and monitoring of behavioural changes especially under stressful conditions. The symptoms and brain changes usually overlap, therefore making it tricky for the exact type of Dementia to be known. Majority of the Dementia cases are handled via a home care provider. This is because there is no cure for Dementia, and home care is usually the best option. Home care service range from feeding, education, supervision to monitoring and health care support. Emotional support is also offered, and mental and psychiatric services are offered in extreme conditions. The provider focuses on making the patient’s life be as normal and ordinary as possible. Prevention of Dementia can be done through change in lifestyle and informed dietary decisions. Therefore, substances like red meat, over-processed food, smoking, drinking alcohol and lack of exercise are discouraged. Mental exercises, nutrient supplements and balanced diet contribute to the prevention and treatment of Dementia. The best treatment however, is love, home care and support from loved ones and the care giver.
