GerontologyGerontology is the science of old age and the aging process. It encompasses the understanding, prevention, rehabilitation, diagnosis, prognosis, and treatment of diseases, disorders, and conditions associated with the changes that occur in humans throughout their entire lifespan, with particular emphasis on longevity.
Old ageOld age is the range of ages for people nearing and surpassing life expectancy. People of old age are called old people, old-timers, the elderly, elders, senior citizens, seniors, or older adults. Old age is not a definite biological stage: the chronological age denoted as "old age" varies culturally and historically.
DiseaseA disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury.

MultimorbidityMultimorbidity, also known as multiple long-term conditions (MLTC), means living with two or more chronic illnesses. For example, a person could have diabetes, heart disease and depression at the same time. Multimorbidity can have a significant impact on people's health and wellbeing. It also poses a complex challenge to healthcare systems which are traditionally focused on individual diseases.

Preventive healthcarePrevention of the occurrence of diseasesImmunization against diseases is a key preventive healthcare measure.Preventive healthcare or prophylaxis is the application of healthcare measures to prevent diseases. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes that begin before individuals realize they are affected.
