Energy Levels in ADHD vs Depression 

In ADHD, energy levels can fluctuate throughout the day. People with ADHD may experience bursts of energy, particularly during stimulating tasks, but often struggle with cognitive fatigue. This mental exhaustion arises from the constant effort needed to focus, control impulses, and complete tasks. As a result, even individuals who appear energetic can feel drained after long periods of concentration. 

In contrast, depression typically causes persistent fatigue and low stamina. Individuals with depression often feel mentally and physically drained, regardless of how much rest they get. This fatigue is constant and can make even simple tasks feel overwhelming. Unlike ADHD, where energy may fluctuate, depression leads to a sustained sense of exhaustion. 

How It Feels: Key Symptoms of Low Energy 

Let’s have a look at the symptoms of low energy in DHD and depression; 

  • Energy in ADHD: Individuals with ADHD may experience bursts of energy but struggle with cognitive fatigue, especially during tasks requiring sustained focus. CBT and medication can help improve focus and manage energy levels. 
  • Energy in Depression: Fatigue in depression is persistent, often accompanied by emotional heaviness. This reduces overall stamina and makes daily activities feel exhausting. Antidepressants and therapy can help alleviate this sense of constant exhaustion. 

Understanding how energy levels in ADHD vs depression differ can guide effective treatment.
