What is hyperfocus?
Adults with ADHD often report episodes of long-lasting, highly focused
attention, a surprising report given their tendency to be distracted
by irrelevant information. This has been colloquially termed
“hyperfocus.” (ADHD, 2019)
Do medications used to treat ADHD decrease hyperfocus?
1) Ozel-Kizil et al, 2016, Hyperfocusing as a dimension of adult attention deficit hyperactivity disorder (Research in Developmental Disabilities)
In the study, they compared individuals >18 years of age diagnozed with ADHD; one group of 53 individuals without medication and another group of 79 individuals treated with stimulants (methylphenidate or SSRIs):
There was no difference between total Hyperfocusing Scale and Adult
ADHD Self- Report Scale scores of two patient groups.
2) Wigal et al, 2012, Adverse events in medication treatment-naïve children with attention-deficit/hyperactivity disorder (Journal of Child and Adolescent Psychopharmacology)
In this study, they were observing side effects of lisdexamfetamine dimesylate for several weeks in 6-12 years old children; in one group they were "stimulant-naive" (not previously treated with stimulants) and in another "previous-exposure subjects".
The stimulant-naïve group reported more trouble sleeping, stomach
pain, and hyperfocus...
The hyperfocus was considered a side effect.
RxList and Drugs.com have lists of side effects of ADHD medications (amphetamine and dextroamphetamine), which could interfere with the ability to focus: restlessness, dizziness, fear, anxiety, sleeplessness, impotence, confusion, nausea, headache, etc.
lose hyperfocus, which is considered one of the advantage of ADHD.)?
