Young-age dementia: Understanding its causes and other aspects
Young-onset dementia (YOD) is a type of dementia that affects individuals under the age of 65. Unlike late-onset dementia, YOD has a wider range of causes, more variable early symptoms, and different social/management needs.
Common causes of YOD include Alzheimer’s disease, frontotemporal dementia (FTD), vascular dementia, and inherited neurodegenerative disorders such as Huntington’s disease. Secondary dementias, which can be related to metabolic, infectious, autoimmune, or neoplastic disorders, also account for a significant portion of YOD cases.
Alzheimer’s disease, including early-onset Alzheimer’s, is a leading cause of YOD. In younger patients, Alzheimer’s disease is often associated with three single-gene mutations: presenilin 2 (PSEN2), presenilin 1 (PSEN1), and amyloid precursor protein (APP).
FTD, which is relatively common in younger people, often presents with behavioral, personality, or language changes due to frontal/temporal lobe damage. Symptoms of FTD include behavior disturbances, personality changes, loss of motivation and empathy, and impulsivity.
Cognitive symptoms, such as problems with memory, word-finding, planning, decision-making, and following stories, are common in YOD. However, memory loss may be less prominent early in some YOD types, such as FTD, compared to typical late-onset Alzheimer’s disease.
Behavioral and personality changes, such as apathy, disinhibition, impulsivity, mood shifts, and loss of social tact, are especially common early in FTD and in many YOD presentations. Language and communication problems, such as progressive aphasia or trouble finding words and following conversations, occur in some YODs.
Diagnosing YOD involves obtaining a comprehensive history, learning a person’s psychiatric, medical, and family history, physical and neurological exams, brain scans, lab tests, genetic testing, imaging tests, and counseling or therapy. Getting an accurate diagnosis early and receiving appropriate support can significantly reduce the distress and confusion that a person and their family may experience.
Treatment for YOD aims to manage the condition and improve quality of life. Cause-directed treatment is given when possible, such as treating reversible causes like vitamin deficiencies or stopping offending medications. Disease-specific pharmacotherapy, such as cholinesterase inhibitors or memantine, may be used in Alzheimer’s disease. Symptom-directed medications, like antidepressants, antipsychotics, or medications for movement symptoms, may also be used when indicated.
Non-pharmacological and psychosocial interventions, such as cognitive rehabilitation, behavioural strategies, structured routines, speech/language therapy, and occupational therapy, are essential in supporting function and safety. Family and social support, including counselling, caregiver support, workplace adaptations, and legal/financial planning, are especially important in YOD due to vocational and family implications.
Multidisciplinary care involving neurology, psychiatry, gerontology/younger-onset dementia services, social work, and specialized memory or dementia clinics improves management.
The prognosis for YOD varies widely by cause. Some neurodegenerative YODs are progressive and incurable, while some secondary causes are treatable and potentially reversible. Acute changes, such as sudden worsening, new hallucinations, or changes in alertness, can indicate delirium from an intercurrent illness and require urgent medical assessment.
In the United States, approximately 200,000 people have young onset Alzheimer's. Recognising dementia in young people can be more difficult due to being younger at the age of onset, having an uncommon type of dementia, and consulting an increased number of services. A person who is concerned may make an appointment with a doctor to ease their worry, provide answers, and help them seek the appropriate support.
Although there is currently no cure for dementia, several treatments can help manage the condition. These include prescription drugs like donepezil, rivastigmine, aducanumab, and memantine, talk therapies, counseling, support groups, financial planning, genetic counseling, community care programs, and online communities like ALZConnected.
