Why do I start tasks and forget about them moments later with ADHD? 

You set out to do one thing, only to find yourself suddenly caught up in something entirely different. If that sounds familiar, you are likely experiencing ADHD task forgetting. This is not laziness or flakiness; it is a cognitive glitch rooted in inattentiveness and short-term memory challenges that are common in ADHD. 

People with ADHD often start tasks with good intentions but struggle to maintain focus when distractions pop up. A phone buzz, a random thought, or even walking into a different room can derail the plan. Once attention shifts, the original task may be mentally dropped, leading to task abandonment that feels as sudden as it is frustrating. 

Why ADHD Makes Task Follow-Through So Difficult 

Here are a few reasons task forgetting is so common in ADHD brains: 

Weak working memory:  

ADHD limits how much information the brain can hold and manipulate in the moment. Visual reminders, to-do boards, or using timers can help keep the task “front of mind.” 

Easily hijacked attention:  

Even small sensory or emotional triggers can shift focus away from the task at hand. Environment structuring and single task focus routines are core strategies used in CBT. 

Impaired transition management:  

Starting is easy; staying with a task through to completion is harder. Breaking tasks into smaller, time-bound chunks can help reduce abandonment.
