Combined-type ADHD is the most common subtype of ADHD, characterised by a dual presentation of both inattentive and hyperactive-impulsive symptoms. Individuals with combined-type ADHD experience the challenges of focus difficulties, restlessness, impulsivity, and a lack of organisation. This mixed set of symptoms can impact various aspects of life, including school, work, and personal relationships.

Unlike the purely inattentive or hyperactive-impulsive subtypes, combined-type ADHD presents a blend of behaviours, making it more complex to manage. Individuals may struggle with attention and focus, often becoming easily distracted or forgetting tasks, while also feeling restless, impulsive, or having trouble sitting still. The combination of these symptoms can make everyday activities more challenging, leading to difficulties in staying organised, meeting deadlines, or maintaining productive routines.

Key Symptoms of Combined-Type ADHD

Here are the key symptoms of combined-type ADHD:

Inattention

Like those with the inattentive subtype, individuals with combined-type ADHD may struggle to focus on tasks, forget instructions, or become easily distracted during conversations or activities.

Hyperactivity and Restlessness

The hyperactive component leads to physical restlessness, difficulty staying seated, fidgeting, or feeling the constant need to move. These symptoms often cause disruptions in environments that require sustained attention, such as classrooms or meetings.

Impulsivity

Impulsive behaviours, such as interrupting others, making decisions without thinking, or engaging in risky activities, are common in those with combined-type ADHD.

In conclusion, because combined-type ADHD involves mixed symptoms, individuals often face challenges in both focusing on tasks and managing their energy levels or impulses.
