AI-Generated Deep Dive Summary
Attention deficit hyperactivity disorder (ADHD) is often viewed as a mental health condition requiring specialized care, but its impact on physical health is equally significant. People with ADHD face higher risks of physical illnesses such as cardiovascular diseases, diabetes, cancers, and neurological conditions. These risks are often modifiable factors like obesity, smoking, and high blood pressure, which can lead to serious health issues like heart attacks or strokes if left untreated. Despite this, many healthcare systems separate mental and physical health services, leaving individuals with ADHD at higher risk of premature death.
The connection between ADHD and premature mortality is a growing concern. Studies have shown that adults with ADHD have a shortened life expectancy of seven to nine years compared to the general population. While some deaths are linked to suicide or accidents, others result from untreated physical health issues in older age. This highlights the urgent need for integrated care that addresses both mental and physical health.
Primary care plays a critical role in bridging this gap. Primary care providers are uniquely positioned to monitor and manage both ADHD and its associated physical health risks. By training primary care staff to take on more comprehensive roles in ADHD care, including managing modifiable health risks, healthcare systems can provide more holistic support. Countries like Australia and the UK are already taking steps to integrate ADHD care into primary healthcare settings
