Symptoms and Effects of Untreated ADHD in Adults

Adult ADHD often goes undiagnosed, as many believe they've outgrown their childhood symptoms. However, ADHD can persist into adulthood, causing significant difficulties such as:

  • Trouble concentrating
  • Difficulty paying attention
  • Impulsivity
  • Hyperactivity
  • Careless mistakes
  • Forgetfulness
  • Mood swings
  • Relationship issues
  • Disorganisation
  • Low self-esteem
  • Missed deadlines

Untreated adult ADHD can also lead to mental health concerns like depression, anxiety, and substance abuse.

The relationship between ADHD and these conditions is complex, with symptoms exacerbating one another and potentially leading to risky behaviours.

It's crucial to seek treatment to manage symptoms and prevent long-term negative consequences. Many adults with ADHD remain undiagnosed and untreated due to a lack of awareness about the disorder in adulthood.

If you think you might have ADHD, take our self-assessment today to see whether or not you present key symptoms.

Diagnosing Adult ADHD

Healthcare professionals use the criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to diagnose adult ADHD. These criteria include symptoms that interfere with daily life, onset before age 12, and persistence for at least six months. Family history may also be considered.

Identifying adult ADHD can be challenging, as symptoms may overlap with other mental health issues or be mistaken for stress or fatigue. Common signs include difficulty focusing, completing tasks, forgetfulness, impulsivity, disorganisation, and poor time management.

If you suspect you have ADHD, seeking a professional diagnosis is essential. A healthcare provider can help you understand your symptoms, discuss treatment options, and access resources and accommodations to make daily life more manageable.

Don't hesitate to reach out for support – a proper diagnosis can be life-changing.

Consequences of Ignoring ADHD Symptoms in Adulthood

Ignoring adult ADHD symptoms can have far-reaching consequences, affecting work, relationships, and finances.

Adults with untreated ADHD may struggle to meet job requirements, miss deadlines, and maintain steady employment, leading to underemployment, unemployment, and financial instability.

Untreated ADHD can also strain personal relationships due to poor communication, misunderstandings, and frustration for all involved. This can put pressure on marriages, friendships, and family bonds.

Other risks include poor time management, organisational difficulties, emotional dysregulation, and car accidents due to inattention or distraction.
Some adults with untreated ADHD may turn to unhealthy coping mechanisms like substance abuse, leading to addiction, health problems, and further personal and professional challenges.

Recognising and addressing ADHD symptoms is crucial for overall well-being and success.

Available Treatments for Adult ADHD

Several effective treatments are available for adult ADHD.

  • Medication, such as stimulants or non-stimulants, is a popular option.
  • Skills training can help young adults develop coping strategies for time management and organisation.
  • Psychotherapy provides a space to learn coping mechanisms and manage symptoms.
  • Environmental modifications, like reducing distractions, can also be helpful.
  • Natural remedies, such as improving sleep hygiene, maintaining a healthy diet, and regular exercise, can also positively impact ADHD symptoms.

Working with a mental health professional is key to determining the best treatment plan for your unique needs. They can help you weigh the benefits and risks of each option and monitor your progress.

Remember, there's no one-size-fits-all approach – the right treatment for you may involve a combination of strategies.
