ADHD and Depression: The Link, the Risks, & When To Seek Treatment


The coexistence of ADHD and depression is not uncommon, and their relationship is multifaceted. Individuals with ADHD may face an increased risk of developing depression, and the challenges associated with both conditions can exacerbate one another.

  • In short: ADHD is characterised by persistent patterns of inattention, hyperactivity, and impulsivity.
  • On the other hand, depression involves enduring feelings of sadness, hopelessness, and a lack of interest in activities once enjoyed.

Understanding the link between these two conditions is crucial for timely intervention and comprehensive mental health support. Today, we’ll explore the intricate connections between ADHD and depression, shedding light on the risks involved and offering guidance on when to seek treatment.

How Are ADHD and Depression Connected?

One question we often hear at The ADHD Centre is: what is ADHD comorbid with? Depression fits squarely within this bracket.

The relationship between ADHD (Attention Deficit Hyperactivity Disorder) and depression is intricate, and their coexistence can significantly impact an individual’s mental health. Several factors contribute to the connection between these two conditions:

  1. Common Neurobiological Pathways: Both ADHD and depression involve alterations in chemical activity, particularly related to neurotransmitters dopamine and serotonin. While ADHD is associated with dysregulation in the dopamine system, depression is linked to imbalances in serotonin (although this is subject to ongoing debate).
  2. Chronic Stress and Coping Mechanisms: Individuals with ADHD often face chronic stress or burnout due to the challenges associated with managing their symptoms. This ongoing stress can be a contributing factor to the development of depression. Coping mechanisms adopted by individuals with ADHD, such as avoidance or procrastination, may amplify stress and contribute to depressive feelings.
  3. Impaired Executive Functioning: ADHD is characterised by deficits in executive functions, such as attention, planning, and impulse control, which often have a cumulative impact and contribute to depressive symptoms.
    Social and Academic Implications: Childhood and adult ADHD often creates challenges in social and academic domains.
  4. Difficulties in forming and maintaining relationships, coupled with academic underachievement, can contribute to feelings of isolation and low self-esteem.
  5. Genetic Factors and Familial Patterns: Research suggests a genetic component to ADHD, and the same is true of depression. Individuals with a family history of either may be more susceptible to developing the other.

ADHD vs Depression

ADHD and depression are comorbid disorders, meaning they can, and often do coexist. However, it’s important to recognise the distinctions between the two. Understanding their unique characteristics is a starting point for accurate diagnosis and appropriate intervention.

Core Symptoms and Diagnosis


  • Characterised by persistent patterns of inattention, hyperactivity, and impulsivity.
  • Individuals with ADHD may struggle with focus, organisation, and impulsivity in various aspects of life.


  • Marked by pervasive feelings of sadness, hopelessness, and a loss of interest or pleasure in activities.
  • Depressive symptoms often affect mood, energy levels, and motivation.

Cognitive Challenges


  • Impaired executive functions, leading to difficulties in tasks such as planning, organising, and time management.
  • Individuals may struggle with forgetfulness and impulsivity.


  • Cognitive symptoms include difficulty concentrating, indecisiveness, and impaired memory.
  • Negative thoughts and self-doubt are prevalent.

Impact on Energy Levels


  • Individuals may experience restlessness and have difficulty sitting still.
  • Hyperactivity is a common symptom, reflecting excess energy.


  • Often associated with persistent fatigue, low energy levels, and a sense of lethargy.
  • Daily activities may feel overwhelming.

Emotional States


  • Emotional dysregulation, quick shifts in mood, and heightened emotional responses.
  • Frustration and impatience are common.


  • Persistent feelings of sadness, emptiness, or irritability.
  • A general sense of despair may accompany depressive episodes.

Social and Interpersonal Functioning


  • Challenges in forming and maintaining relationships due to impulsivity, forgetfulness, and difficulty with social cues.


  • Social withdrawal and isolation are common.
  • Depressive symptoms may strain relationships.

Response to Stress


  • Stress often exacerbates ADHD symptoms, leading to increased restlessness and impulsivity.


  • Stress may deepen feelings of hopelessness and contribute more to a sense of being overwhelmed.

Overlapping Symptoms

Despite possessing distinct characteristics, these conditions can exhibit overlapping symptoms and triggers, sometimes making ADHD diagnosis and differentiation challenging.

It’s equally important to acknowledge the following shared features, as they can complicate the clinical picture:

  • Difficulty concentrating
  • Emotional dysregulation
  • Struggles with planning, time management, and organisation
  • Fatigue and low energy
  • Sleep disturbances
  • Social withdrawal
  • Procrastination and avoidance

ADHD and Depression In Adults

The social, professional, and occupational difficulties associated with untreated ADHD, such as job instability, relationship conflicts, or financial stress, can act as significant stressors. These stressors increase the risk of developing depression in adults.

Persistent struggles with ADHD symptoms may impact self-esteem and identity formation. Adults with ADHD sometimes grapple with feelings of underachievement, leading to a negative self-perception and, in turn, contributing to depressive thoughts.

In turn, the chronic stress of constantly managing ADHD symptoms can contribute to burnout. As burnout sets in, individuals may experience a decline in mental health.


ADHD and Depression In Children

Imagine a 10-year old child with ADHD who consistently forgets to complete homework assignments, experiences difficulty concentrating in class, and faces frequent reprimands from teachers. Over time, these struggles may contribute to a sense of inadequacy and sadness.

Similarly, ADHD-related impulsivity and hyperactivity can affect a child’s ability to form and maintain friendships. Social rejection or isolation may become sources of stress, impacting the child’s emotional well-being.

And, at home, the demands of parenting a child with ADHD can create additional stress within the family.

Balancing the needs of a child with ADHD while addressing the emotional toll on parents and siblings can contribute to an environment where depressive symptoms may emerge.


Treatments For ADHD and Depression

Depending on the individual case, a healthcare or mental health professional may recommend medications to treat ADHD and its symptoms – the same goes for depression. ADHD medications (such as stimulant medications), carefully prescribed and monitored, can play a role in improving concentration, mood regulation, and overall well-being.

That said, behavioural coaching is often instrumental in treating ADHD and depressive symptoms. By targeting challenging thought patterns and building coping mechanisms, therapy equips individuals with valuable support skills to manage challenges.

For all of us, mindfulness techniques enhance our ability to manage stress, anxiety, and emotional dysregulation. When made a part of daily routines, mindfulness contributes significantly to well-being, and a healthy lifestyle – including regular physical activity, balanced nutrition, and sufficient sleep – forms a foundational aspect of managing ADHD and depression symptoms.
