The Long-Term Effects of Untreated ADHD in Adults
When you are diagnosed with ADHD as an adult, it can cause a variety of emotions. It could bring feelings of grief over missed opportunities or satisfaction that you now have a concrete explanation for your struggles.
Untreated ADHD can have a long-lasting impact on relationships and financial stability, mental health and much more. It is important for providers to think about the long-term implications of untreated ADHD in adults.
1. Mental Health Issues Increased Risk

Adults who suffer from untreated ADHD may have trouble managing negative emotions, especially when faced with challenges and setbacks. For instance, someone who is not treated for ADHD might forget significant dates or react impulsively in sensitive conversations, which can affect relationships. They might also fail to meet deadlines or make careless mistakes in professional settings, which can affect trust and dependability. This can result in feelings of anger or inadequacy and an image of self-doubt.
Adults who suffer from untreated ADHD might also face financial issues due to their lack of attention and disorganization as well as impulsive behavior. For instance, they could spend money in a hurry and do not keep track of their bills or fail to pay their phone bill on time, which could result in late fees or overdue payments. They may also have difficulty keeping a steady job due to frequent job changes and struggles with attention, organization, and time management.
Undiagnosed ADHD has been linked to higher levels of mental health issues, including depression and social problems (Bishop Fitzpatrick et. al. 2018), and a greater risk of engaging in sexually unsafe behaviors (Bargiela and al. 2016). Additionally, it has been linked to lower quality of life and increased risk of developing chronic health conditions like obesity and heart disease.
Adults who suffer from untreated ADHD might benefit from psychoeducation and therapy. They can also reduce the risk of developing co-occurring disorders by keeping an eye on their symptoms and avoiding certain medications that may be associated with them, like stimulants. They should also be open and honest with their health care provider about their symptoms and how they affect their daily life and allow them to prescribe medication that is most effective for them.
2. Increased Risk for Substance Use Disorders
A comorbid diagnosis of ADHD and substance use disorder (SUD) is all too common for people who suffer from untreated ADHD. ADHD symptoms like inattention and impulsivity can lead to drug addiction and alcohol dependence. Someone with ADHD has a higher risk of becoming dependent on alcohol and other drugs than someone without ADHD. This is believed to be due to the main ADHD symptoms of impulsivity and poor self-regulation, which can cause a higher chance of experimenting with drugs and alcohol consumption.
The combination of low dopamine levels and impaired dopamine receptors triggered by untreated ADHD can also increase the risk for drug addiction. Drugs that stimulate the brain such as Ritalin or Adderall are frequently used to treat ADHD. They increase dopamine levels in the brain, and aid in helping people to focus and remain calm. However, long-term use of stimulants could cause serious side effects like stroke, heart attack, brain damage and even death.
Untreated ADHD can lead to depression and suicidal thoughts. This can lead to addiction. Untreated ADHD can also cause relationship and work problems. Untreated ADHD can also lead to financial problems that make it difficult for people to maintain the right health insurance coverage.
Getting a diagnosis of ADHD in adulthood can come as a relief to many adults, allowing them to recognize that their behavior isn't their own fault. Adults suffering from ADHD should seek treatment. First, adult adhd diagnosis and treatment should consult with a physician to receive an accurate medication assessment and receive the best medications for your specific needs. Be sure to disclose any other health conditions or medications you are taking for, as certain ADHD medications may interact with certain substances.
3. Increased risk of depression and anxiety
Untreated ADHD can have lasting consequences that impact a person's quality of life. These include difficulties at work, home and in social interactions. There are also feelings of low self esteem, a pessimistic outlook and depression.
Adults with ADHD may have trouble maintaining friendships or managing relationships because they are indecisive and forget important dates or aren't paying attention. Adults suffering from untreated ADHD might also have trouble managing long-term projects and navigate the workplace hierarchy due their inability to meet deadlines. In some cases this may cause unemployment, lower occupational status, and higher levels of job anxiety and stress.
Ginsberg and colleagues (64) conducted an extensive review of outcomes associated with underdiagnosis and inadequate treatment for ADHD. Their findings revealed that untreated ADHD affects academic performance negatively as well as psychiatric and co-morbidities, substance use, employment, antisocial behavior driving, and health (e.g. obesity, smoking and poor sleep).
In addition to receiving an accurate diagnosis of ADHD Some adults can are able to benefit from other treatment strategies. These include behavioural interventions like behavioral therapy, as well as lifestyle changes such as a healthier diet and exercise. Some individuals with ADHD might also benefit from medication. Stimulants like dextroamphetamine or methylphenidate, also known as Ritalin (Ritalin), may be prescribed. Medication trials start with a small dose to see how the individual responds, before increasing the dosage.
It is important to get a correct diagnosis and start treatment as soon as possible to control ADHD symptoms. The symptoms can be similar to those of other disorders, such as depression and anxiety, which is why it's important to get a thorough evaluation by medical professional or mental health professional to determine what is the reason for these symptoms.
4. Increased Risk for Physical Health Issues
Adults who suffer from untreated ADHD may find it difficult to maintain their regular healthcare routines. They may miss appointments, have difficulty getting prescriptions filled, and struggle with adherence to the diet, sleep and exercise routines. This can cause health issues like heart disease and hypertension. They may also have difficulty managing financial issues, which can result in impulse spending or late payment of bills. This can lead to the development of chronic health issues that stem from mental disorders that are underlying such as depression and anxiety.
Untreated ADHD can make it difficult for people to maintain their social networks and relationships. Relationship problems can be caused by their symptoms, which include forgetting household chores, ignoring their partners, or getting easily distracted when talking to others. They may also be unable to remember important occasions like birthdays or anniversaries. This can create tension and stress in their romantic relationships, which can ultimately result in a breakup.
Many adults can improve their quality of life by making lifestyle changes and managing symptoms. They can make use of lists to help manage their forgetfulness. They can establish regular daily routines to reduce the variability. And they can engage in physical activity to help them conquer their agitation. They can also consult with a doctor to develop an appropriate medication dosage that will help improve their symptoms but not cause any negative adverse side negative side effects.
It's important to seek help if you are struggling with the symptoms of ADHD. In the absence of treatment, it could lead to people blaming their challenges on themselves, focusing on the issues and triggering a cycle that negatively affects their physical and mental well-being. Early diagnosis and treatment will help prevent these problems.
5. Increased Suicide Risk
It is not unusual for those with untreated ADHD who are diagnosed to engage in self-destructive strategies to cope. This can include drinking or using drugs that may lead over time to other mental health issues and lead to a downward cycle of symptoms.
People who suffer from ADHD may also have difficulty maintaining relationships due to their impulsivity, and may struggle to manage emotions. They might not be able to attend important events or drop off the track in conversations, leaving their loved ones feeling undervalued and frustrated. They may also carelessly agree to something and then later regret it, which could cause tension in friendships. In the workplace, those who suffer from untreated ADHD often fail to meet deadlines and lose credibility due to of their disorganization and inability to keep their commitments.
Unfortunately, the challenges that arise from living with ADHD can be a recipe for anxiety and depression, which can also result in suicide attempts. If not treated, ADHD is associated with a higher likelihood of suicide regardless of whether comorbidities are present. It also found that adult ADHD-related impulsivity and hyperactivity predicted temper outbursts/hitting/throwing and that adult ADHD-related inattention predicted threats/actual self-harm.
However, it should be noted that the subjects in the study were primarily female, and only a tiny percentage of them had a diagnosis of ADHD-H. Therefore, future research should aim for larger sample sizes to ensure accurate results. Furthermore, the research was based on questionnaires, so results should be validated using diagnostic interviews.
