The Long-Term Effects of Untreated ADHD in Adults
Receiving a diagnosis of ADHD as an adult can create complicated emotions. It can bring feelings of regret over missed opportunities or relief at finally finding a cause for your struggles.
Untreated ADHD could have a long-lasting impact on relationships and finances, mental health and more. It is important that providers consider the long-term consequences of untreated ADHD among adults.
1. Higher Risk of Mental Health Issues
Adults suffering from untreated ADHD might have difficulty coping with negative emotions, especially in the face of challenges and setbacks. For instance, a person who is not treated for ADHD may forget important dates or be impulsive in sensitive conversations, which can strain relationships. They might also fail to meet deadlines or make a mistake in professional settings, which can affect trust and reliability. In some cases it can increase feelings of discontent and unworthiness which can create a negative self-image.
Adults who suffer from untreated ADHD might also face financial issues due to their inattention, disorganization and unpredictable behavior. For instance, they may spend money in a hurry or fail to keep track of bills or forget to pay their phone bill on time, which can result in late fees or overdue payments. They might also have trouble maintaining stable employment due to frequent job changes and issues with attention, organization, and time management.
Studies show that undiagnosed ADHD is associated with higher rates of mental health issues, such as anxiety and depression (Able and al. 2007) and social issues (Bishop-Fitzpatrick and co., 2018) and a greater susceptibility to sexually harmful practices (Bargiela and al. in 2016). It has also been associated with a lower standard of life and an increased risk of chronic diseases such as heart disease and weight gain.
Adults who suffer from untreated ADHD might benefit from psychoeducation and therapy. They can also learn to reduce their risks of co-occurring conditions by keeping a close eye on their symptoms and making sure they don't take certain medications, such as stimulants, that could interfere with them. They should also be forthcoming and honest with their doctor about their symptoms and how they affect their daily life, which will allow providers to prescribe medications that are most effective for them.
2. Higher Risk for Substance Use Disorders
A comorbid diagnosis of ADHD and substance use disorder (SUD) is all too common for those living with untreated ADHD. Inattention and impulsivity two ADHD symptoms that can result in alcohol and drug abuse are frequent. Studies have found that a person who suffers from ADHD is more likely to become addicted to drugs and alcohol than people who don't have ADHD. This is believed to be due the core ADHD symptoms, impulsivity and low self-regulation. These can lead to an increased risk of and alcohol use.
The combination of low dopamine levels and impaired dopamine receptors triggered by untreated ADHD can also increase the risk of addiction to drugs. Stimulants such as Ritalin or Adderall are often used to treat ADHD. They boost dopamine levels in the brain, and help people concentrate and remain calm. However, long-term use of stimulants may cause serious negative side effects, like stroke, heart attack, brain damage and even death.
People who are not treated for ADHD might be more likely to suffer from depression and are at a greater chance of having suicidal thoughts which can lead to substance abuse. Additionally, many people who suffer from untreated ADHD struggle with relationship and work issues. Untreated ADHD may also cause financial problems that make it difficult for people to maintain adequate health coverage.
Many adults can feel relieved when they receive a diagnosis of ADHD as an adult. They are now aware that their behavior wasn't their fault. However, it is important for people suffering from ADHD to seek treatment. First, you must consult an expert for a proper medication assessment and to receive the most effective medication for your specific needs. The disclosure of any health issues or medications is crucial since certain ADHD medications can interact with certain substances.
3. Increased risk of depression and anxiety
Untreated ADHD can have long-lasting effects that impact a person's quality of life. This can be a problem at work, home, and in social interactions. There are also feelings of low self esteem, a pessimistic outlook and depression.
Adults who suffer from ADHD are often unable to maintain relationships or maintaining friendships because they are impulsive and forget important dates or aren't paying attention. Additionally, those with untreated ADHD often have difficulty navigating workplace hierarchies and managing long-term projects due issues with keeping deadlines. This can lead to joblessness, decreased occupational status and higher levels of stress and anxiety.
Ginsberg and his coworkers (64) conducted an extensive review of the outcomes of ADHD underdiagnosis. Their findings indicated that untreated ADHD can have negative effects on academic performance and psychiatric comorbidities, drug abuse as well as on employment, antisocial behavior, driving, and physical health (e.g., smoking, obesity and sleep problems).
Some adults can benefit from other treatments in addition to receiving an accurate diagnosis of ADHD. These include behavioral therapies like behavioral therapy and lifestyle modifications like improved diet and exercise. Certain individuals suffering from ADHD may also benefit from taking medication. stimulants such as dextroamphetamine and the methylphenidate, which is also known as Ritalin (Ritalin) can be prescribed. To begin with evidence based treatment for adhd in adults , the medication is administered at a low dosage to determine how a person responds.
It is important to get a correct diagnosis and begin treatment as soon as possible to treat ADHD symptoms. Symptoms can also mimic those of other illnesses, such as anxiety and depression, so it is essential to have an accurate assessment by a health care provider or mental health professional to determine what is the reason for these symptoms.
4. Increased Risk for Physical Health Problems
Adults with untreated ADHD may find it difficult to maintain their regular healthcare routines. They may be late for appointments, have difficulty filling prescriptions, and struggle with adherence to eating, sleeping, and exercise schedules. This can lead to health problems such as hypertension and heart disease. They may also have difficulty dealing with financial issues, resulting in impulse spending or late payment of bills. This can also exacerbate chronic health conditions that result from mental disorders, such as depression and anxiety.
Untreated ADHD can make it difficult for people to maintain their social networks and relationships. Their symptoms, such as not being able to complete household chores or ignoring their partner getting easily distracted during conversations, can cause problems with relationships. They may also have trouble remembering important dates, such as birthdays or anniversary celebrations. This can cause tension and anxiety in their relationships.
For many adults, symptom management and lifestyle changes can make significant improvements in the quality of life. They can use lists and reminders to manage their forgetfulness, develop structured daily routines to reduce the amount of variability and also engage in physical activities to help them overcome restlessness. They are also able to work closely with their physician to determine the right medication dosage that will aid in improving their symptoms while minimizing any side consequences.
It is crucial to seek help if you are struggling with the symptoms of ADHD. Patients who put off treatment may end up blaming themselves for their struggles, seeing them as character flaws, and creating a vicious cycle that has negative effects on both their mental and physical health. Making sure you have a clear diagnosis and undergoing treatment as soon as is possible will help prevent these complications from developing.
5. Suicide Risk Increased

A diagnosis of ADHD could be misinterpreted as a character flaw, and it is not common for those with untreated ADHD to turn to self-destructive or harmful coping mechanisms. This may include using alcohol or drugs. This can cause mental health issues later on and cause the deterioration of symptoms.
In addition, those who suffer from ADHD may have difficulty maintaining relationships due to their impulsivity as well as difficulty managing their emotions. They may 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 agree to an unwise decision and then regret it. This can affect friendships. Adults suffering from untreated ADHD are often disorganized and lose their credibility at work because they can't keep their promises.
The difficulties associated with living with ADHD may lead to depression and anxiety. These can also lead towards suicide attempts. A study has found that those who suffer from untreated ADHD are at a greater risk likelihood of suicide, regardless of comorbidities. 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 participants in the study were primarily female, and only a tiny percentage of them had been diagnosed with ADHD-H, so future research should aim for larger samples to ensure reliable results. Additionally, the studies were built on questionnaires, which means that results should be confirmed using diagnostic interviews.
