Summary: Grownups taking large doses of amphetamine-based medicines for ADHD, such as Adderall, experience a five-fold increased risk of developing schizophrenia or insanity. The danger was highest for those taking 30 grams or more of adderall, with 81 % of psychosis or insanity cases probably unnecessary by lowering the dosage.
This research emphasizes the importance of dose, despite earlier research linking substances to these risks. People who are at higher chance for mental health issues should be closely monitored by doctors, particularly those who are.
Important Information:
- High dosages of ADHD medications is fivefold increase the risk of illness or mania.
- 81 % of cases of illness or madness could have been avoided with less medication.
- Methylphenidate ( Ritalin ) did not show a similar increase in psychosis risk.

Prescribing rates for stimulants that treat attention-deficit/hyperactivity disorder ( ADHD ) have increased significantly over the past decade, with some of the largest increases reported during the COVID-19 pandemic.
A new study of adult emergency department admissions at Mass General Brigham, led by McLean Hospital researchers, found that people who are taking high amounts of amphetamine ( such as Adderall ) are more than five times more likely to experience psychosis or mania.
Findings were published September 12th , in the , American Journal of Psychiatry.
Ultimately, those who used past-month prescribed amphetamines had a higher risk of mania or new-onset psychosis than those who used them. According to the study, those taking 30 mg or more of dextroamphetamine ( which corresponds to 40 mg of Adderall ) had the highest risk.
Stimulants have been linked to illness and insanity risk in earlier studies, but little information has been provided regarding whether dosing had an impact on risk.
Lead sturgeon said:” Stimulant medications do n’t have an upper dose limit on their labels, and our results demonstrate that it is obvious that dose is a factor in psychosis risk and should be a top consideration when prescribing stimulants.
udy artist Lauren Moran, MD, a pharmacoepidemiology scholar at McLean Hospital. This is a uncommon but significant side effect that should be monitored by both the patient and the doctor whenever these drugs are prescribed.
Moran claimed that her research was the result of her prior hospital physician clinical observations. She and her McLean colleagues may frequently observe patients who were experiencing their first psychosis episodes, and their health records would reveal that their doctors had prescribed them large amounts of stimulants.
The study focused on adults between the ages of 16 and 35, the usual time for schizophrenia and psychosis, and examined electronic health records of Mass General Brigham person contacts between 2005 and 2019. Following recommendations from different Massachusetts General Brigham healthcare systems, all patients were admitted to McLean Hospital.
In contrast to 2, 748 handle patients in a psychiatric treatment for other problems like depression or worry, the researchers found 1, 374 cases of people presenting with first-episode illness or mania.
In order to determine the effects of stimulants, they conducted a comparison study of drug employ over the previous month and took into account different factors, including substance use.
They discovered that the related risk percentage for those exposed to any prescription opioid was nearly 63 %, and for higher dose adderall was 81 %. These findings suggest that 81 % of illness or madness could have been avoided among those taking prescription opioid if not the higher dosage.
While a significant dose-related risk increase was seen in patients taking high doses of amphetamine, no significant risk increase was seen with methylphenidate ( Ritalin ) use, which is consistent with previous research, including a , 2019 study led by Moran.
The research does not establish causality, but the researchers do point out that there is a realistic physiological mechanism for pharmacological changes, such as higher levels of dopamine release from amphetamines, that are similar to cholinergic changes seen in psychosis.
The study’s limits include irregularities in how electronic health records are kept. Moreover, the findings may be less applicable to different parts of the country because the research is being conducted in a psychiatric doctor in the Boston area, which sees many individuals with illness.
Moran argued that the findings should not raise alarms, but rather that extra caution should be exercised when prescribing these medications, particularly for those with schizophrenia and madness risk factors.
” There’s limited evidence that prescription stimulants are more successful in high dosages”, said Moran. Physicians should take into account other less dangerous medications, especially if a person is at high risk for mania or illness, according to our study.
