Purpose: To explore the burden of illness and impact on patients' quality of life (QoL) experiences in older ADHD adults.
Methods: Telephone interviews were conducted with older adult participants diagnosed with ADHD later in life. Transcripts were analyzed following a grounded theory approach.
Results: Mean age of participants (N = 24) was 66 years, and mean age at diagnosis was 57 years; 68% were men and 63% reported other comorbid mental health conditions. ADHD symptoms reported were inattention (71%), impulsivity (58%), hyperactivity (54%), and disorganization (54%). The majority of participants (63%) experienced an accumulated lifetime burden of illness and reported being financially less-well-off, had lower educational achievement, job performance, and greater social isolation due to their ADHD. Older adults reported significantly greater impairments in productivity (P ≤ 0.02) and a better life outlook (P ≤ 0.05) than younger ADHD adults.
Conclusions: Older adults' QoL suffers from the accumulative negative impact of ADHD symptoms/impairments on their professional, economic, social, and emotional well-being.
