Does forgetting appointments suggest ADHD? 

Author: Avery Lombardi, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

If you frequently forget appointments or other important commitments, it could be a sign of ADHD memory issues. While forgetfulness is common for everyone from time to time, for individuals with ADHD, it can be a persistent problem that significantly impacts daily life. Forgetting appointments is often linked to underlying challenges such as executive dysfunction and planning problems, which are hallmark symptoms of ADHD. 

For people with ADHD, managing time, planning, and remembering appointments can be particularly difficult. Executive dysfunction affects the brain’s ability to organise, prioritise, and follow through on tasks. This can lead to missed meetings, forgotten deadlines, or overlooked personal commitments. 

Why forgetting appointments can suggest ADHD 

Here’s how ADHD memory issues and executive dysfunction contribute to forgetfulness: 

Difficulty with planning  

People with ADHD often struggle to break tasks into smaller steps and follow through on plans. This leads to missed appointments and forgotten tasks. 

Time management challenges  

ADHD can cause “time blindness,” where it’s difficult to estimate how much time has passed or how long a task will take. This can result in appointments being missed or forgotten. 

Distraction and lack of focus  

Due to distractibility, those with ADHD may focus on other things and forget the commitment entirely, even if it was initially on their radar. 

In conclusion, if forgetting appointments is becoming a regular issue and it’s affecting your life, it may be time to explore the possibility of ADHD. Addressing these symptoms early can help develop effective strategies for managing ADHD memory issues and improving organisation.
