Why Are Girls Often Diagnosed with Mood Disorders Instead?
Girls with ADHD are often misdiagnosed with mood disorders due to the symptom overlap between ADHD and conditions like anxiety and depression. The way ADHD presents in girls is often more subtle and internalised compared to the hyperactive, impulsive symptoms seen in boys, leading clinicians to attribute emotional symptoms to mood disorders instead of ADHD. This comorbid misdiagnosis delays the correct treatment, leaving girls struggling with untreated ADHD symptoms.
Why Are Girls with ADHD Misdiagnosed with Mood Disorders?
Several factors contribute to why girls with ADHD are often diagnosed with mood disorders instead of ADHD:
Symptom overlap
ADHD and mood disorders share many overlapping symptoms, such as irritability, emotional dysregulation, and difficulties with concentration. In girls, inattentive ADHD symptoms like daydreaming, forgetfulness, and poor time management are often misinterpreted as signs of depression or anxiety. This symptom overlap makes it harder for clinicians to differentiate between ADHD and mood disorders.
Subtle presentation of ADHD in girls
Girls with ADHD tend to exhibit subtle symptoms compared to boys, who typically display more overt hyperactivity and impulsivity. Because ADHD in girls often presents as inattention, emotional sensitivity, and social difficulties, these symptoms are less disruptive and may be overlooked or dismissed. Clinicians are more likely to focus on mood-related symptoms, assuming that anxiety or depression is the cause, rather than recognising ADHD.
Social expectations and gender norms
Society often expects girls to be emotionally regulated, organised, and socially well-adjusted. These gender norms can cause girls to internalise their struggles, leading them to hide or mask their ADHD symptoms. As a result, their comorbid misdiagnosis as mood disorders becomes more likely, especially when emotional symptoms are more visible than cognitive or behavioural ones.
Under-recognition of ADHD in girls
Historically, ADHD has been under-recognised in girls, particularly because the condition was initially studied primarily in boys. The traditional ADHD diagnostic criteria have been designed based on male symptomatology, which often results in girls with ADHD being misdiagnosed or not diagnosed at all. This is especially true for girls whose ADHD symptoms do not match the more obvious hyperactive and impulsive behaviours commonly associated with the condition.
The Consequences of Misdiagnosis
When girls with ADHD are misdiagnosed with mood disorders, the consequences can be far-reaching. They may receive treatment for anxiety or depression that does not address the underlying ADHD, which means their challenges persist. Left untreated, ADHD can negatively impact academic performance, self-esteem, relationships, and overall well-being.
Properly identifying ADHD in girls and distinguishing it from mood disorders is crucial to ensuring they receive the right treatment and support.
