Diagnosing adult ADHD involves a comprehensive evaluation by a healthcare professional, typically a psychiatrist, psychologist, or other specialists in mental health. The diagnostic process includes a thorough review of the individual's medical history, an assessment of their current symptoms, and the ruling out of other possible conditions that could mimic ADHD symptoms. The healthcare provider may ask about the individual's childhood behaviors and difficulties, as ADHD symptoms typically appear before the age of 12. The diagnosis is made using criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which includes a specific set of symptoms related to inattention and hyperactivity / impulsivity.

In addition to symptom assessment, a detailed interview may be conducted to explore the individual's current struggles in personal, social, and occupational life. It's important for adults to provide specific examples of how their symptoms affect day-to-day functioning. In some cases, self-report questionnaires or ADHD rating scales are used to help track symptoms and compare them with standardized criteria. The doctor may also ask for feedback from family members, close friends, or co-workers who can provide insight into the individual's behavior over time. This holistic approach ensures that ADHD symptoms are not mistaken for other conditions, such as anxiety, depression, or learning disabilities, which may present with similar signs.

The early warning Signs of Depression often include subtle changes in mood, behavior, and physical well-being that may be easy to overlook. Persistent sadness or feelings of emptiness, even in situations where these emotions seem disproportionate, are common early indicators. Individuals may also experience a loss of interest or pleasure in activities they once found enjoyable, such as hobbies, social events, or spending time with loved ones. This disinterest in daily life is often accompanied by fatigue, where tasks that were once manageable become overwhelming or exhausting.

Other early signs of Depression include changes in sleep patterns, such as insomnia or sleeping too much, and changes in appetite, either overeating or losing interest in food. Difficulty concentrating, making decisions, or remembering things can also signal the onset of depression. Emotional symptoms like irritability, guilt, or feelings of worthlessness may begin to surface. If these signs persist for more than two weeks and interfere with daily functioning, it's essential to seek professional help, as early intervention can prevent the worsening of symptoms and lead to better outcomes.
