What is Adult ADHD and How Is It Different to Adult ADD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurobiological disorder characterized by persistent conditions of distractibility, impulsivity, and hyperactivity. In adults, ADHD affects the functioning of complex mental processes such as concentration, motivation, problem-solving, working memory and sustained attention, making everyday life a challenge.
Attention Deficit Disorder (ADD) is a condition similar to Attention Deficit Hyperactivity Disorder, but without hyperactive symptoms, such as constant fidgeting, pacing and nail biting.

ADD and ADHD Symptoms in Adults

Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder symptoms in adults are less conspicuous than those seen in children, and can be in a varying spectrum of severity. The symptoms and severity associated with each individual are unique, and so is the level of impairment caused by adult ADD/ADHD.

The most common symptoms of ADD in adults are:

  • Inability to concentrate for an extended period of time
  • Poor executive functioning
  • Hyperactivity or extreme restlessness
  • Disorganisation such as poor planning, prioritising & time management skills
  • Inability to multi-task and complete tasks
  • Poor attention to detail
  • Impulsivity characterized by complete lack of patience
  • Inability to make decisions
  • General forgetfulness
  • Lack of focus

In addition to the above symptoms, adults with ADD/ADHD often face high levels of stress and anxiety which results in various emotional challenges such as low self-esteem, high level of insecurity, inability to stay motivated and constant irritability.

Adults with ADD/ADHD are also six times more likely to develop an additional cognitive or affective disorder, such as depression, chronic stress, or anxiety.

How Do I Know If I Have Adult ADD/ADHD?

An adult with ADD or ADHD that requires therapy would persistently lack the ability to focus their attention and may consistently display impulsive/hyperactive symptoms which affect their ability to function, perform and develop. This can drastically limit professional growth, academic abilities and affect personal relationships.

Adults with these disorders may feel as though they are driven by a motor, often feeling restless, distracted, and starting a task but not finishing it. They are often unable to see ideas through, and are invariably disorganised.

Some adults with ADD/ADHD might also find themselves making rash decisions because it is too much effort to concentrate, focus and think things through in detail - they will take a hit and miss approach, even in a situation where important decisions need to be made.

If this sounds familiar, and you feel that ADD/ADHD may be causing significant impairments in your ability to function in different aspects of your daily life, Psymplicity’s dedicated team of adult ADD/ADHD experts are here to help.

Q: Are Adult ADHD & ADD the Same?

No, the terms are sometimes used synonymously, but there are key differences between adult Attention Deficit Hyperactivity Disorder and Attention Deficit Disorder - namely that ADHD patients also experience symptoms associated with hyperactivity, such as continuous movement and fidgeting.

Q: How is ADHD/ADD Diagnosed in Adults?

Diagnosing Attention Deficit Hyperactivity Disorder in adults is different from the process used for children and adolescents. At Psymplicity Healthcare London, an ADHD specialist will assess your condition and design a unique treatment plan which is perfectly suited to you. This is outlined above, in our three-step adult ADD/ADHD treatment plan.

Q: How Does ADHD Affect Adults?

If left untreated, Adult ADHD can have adverse effects on an individual’s personal life, professional skills, and overall well being. Constant forgetfulness, impatience and lack of appropriate social skills may cause an inability to build healthy relationships with friends and family. A lack of focus and inability to complete tasks effectively can stunt their professional growth.

Q: Can Adult ADHD/ADD Make You More Prone to Other Psychiatric Conditions?

Adults with Attention Deficit Hyperactivity Disorder are six times more likely to develop a cognitive or affective disorder in addition to their ADHD such as depression, chronic stress, or anxiety.

Q: Which Adult ADHD/ADD medication is best for me?

While there are many medications available for the treatment of adult ADHD/ADD, it is important to take a holistic approach to your treatment plan. This involves our specialist team carefully evaluating your symptoms and conditions before we recommend a personalised treatment that is bespoke to you, and which may or may not require medications.

Q: Can Adult ADHD/ADD be Cured?

Adult ADHD/ADD is a condition that does not have a definitive cure. However, with the right combination of counseling, treatment, and medication tailored to your needs, you will be able to manage the symptoms of your condition and enjoy better clarity, confidence and concentration at work, home and in your daily life.

Q: Where Does Adult ADHD/ADD Come From?

While the exact cause for adult ADD/ADHD cannot be determined, scientific research suggests there are three factors:

  • Genetics: ADHD can be a condition commonly found in families;
  • Environmental factors: Exposure to certain environmental factors such as stress or chemicals such as lead exposure during childhood;
  • Development issues: Disruptions to central nervous development such as brain injury during childhood.
