ADHD vs Bipolar disorder can sometimes be challenging to differentiate, especially when symptoms like low energy, procrastination, or difficulty following through on tasks are present. However, the root causes of these behaviours differ significantly, and understanding these symptom differences is crucial to avoid misdiagnosis and ensure the right treatment.

ADHD Symptoms: Consistent Inattention and Disorganisation 

ADHD is characterised by ongoing issues with attention, impulsivity, and hyperactivity (in some cases). People with ADHD often struggle to initiate and complete tasks, stay organised, and maintain focus. This can lead to laziness-like behaviours, but the root cause is executive dysfunction, difficulty with the brain’s ability to manage time, stay on task, and maintain motivation, especially for tasks that are not immediately stimulating. These struggles are chronic and persistent across various situations and settings. 

Bipolar Disorder Symptoms: Extreme Mood Fluctuations 

In contrast, Bipolar disorder involves distinct mood swings, including manic and depressive episodes. During depressive phases, individuals may experience fatigue, low motivation, and an inability to complete tasks, which can be mistaken for laziness. However, the difference lies in the cyclical nature of bipolar symptoms. People with bipolar disorder experience extreme highs (mania) and lows (depression), and the laziness-like behaviours during depressive episodes are a temporary part of the cycle, not a chronic issue. 

The Risk of Misdiagnosis 

Because both ADHD and bipolar disorder can involve energy and focus issues, there’s a risk of misdiagnosis, especially if the symptoms are not properly assessed. It’s crucial to work with a mental health professional who can distinguish between the symptom differences to provide accurate diagnosis and effective treatment.
