Signs and symptoms of ADHD in adults.
ADHD is widely associated with a persistent pattern of inattention, hyperactivity, and impulsivity. These can significantly impair functioning on a daily basis and affect quality of life.
While the specific characteristics and severity may vary depending on the individual, these are common signals that ADHD may be present:
Inattention
Having difficulty in sustaining attention or staying focused, particularly on tasks or activities, that are repetitive or require a sustained amount of mental effort. →
Hyperactivity
Hyperactivity can be physical or mental. Physical hyperactivity might present as constant fidgeting, squirming or, restlessness →
Impulsivity
Interrupting conversations or activities, blurtings out answers before questions have been completed or completing other people’s sentences. Difficulty waiting their turn in conversation and activities. →
Most people will experience these difficulties to some degree across their lifetime. In order to meet criteria for diagnosis however, these difficulties should have significant impact upon a person’s daily functioning across more than one area of life.
Living with ADHD can be mentally and physically exhausting. It can lead to anxiety, depression and low self-esteem. Some people feel that they cannot keep up with life’s demands and perceive themselves as a failure. Others over-compensate with over controlling perfectionistic routines which can present a little like OCD type traits. It is not uncommon for people with ADHD to experience other mental health difficulties. However, for some, what they perceived to be anxiety or depression may well be undiagnosed ADHD.
Some people may be tempted to self-diagnose themselves with ADHD. If ADHD is suspected, a full assessment from a qualified healthcare professional is recommended. A comprehensive assessment will take into account a person’s life history, from before birth to their current age, as well as utilising objective measures to genuinely understand their life experience. This aids greater understanding of the presenting difficulties and can either aid accurate diagnosis of ADHD or support understanding of other mental health or developmental difficulties.
ADHD diagnosis is the first step to a person understanding themselves better. Following this there are several interventions which can support the management of symptoms. These include, psychological interventions, lifestyle changes, environmental adjustments and medication. Whichever treatment is right for you, it should aim to alleviate symptoms, improve functioning, and enhance your overall quality of life.
