Abstract

Perinatal anoxia/ischemia or premature birth increases the risk of developing attention deficit/hyperactivity disorder (ADHD). Brain imaging studies of idopathic ADHD reveal elevated dopamine transporter density in striatum of patients, predicting abnormal response to a challenge with methylphenidate in this population. We hypothesized that the severity of attention deficit in adolescents should correlate with the sensitivity to psychostimulant-evoked dopamine release. To test this hypothesis, we investigated six adolescent subjects (mean age 14.2 +/- 2.4 yr) with documented birth trauma and/or low birth weight and a diagnosis of ADHD. Using positron emission tomography (PET), we measured the relative binding of [(11)C]raclopride to dopamine receptors in striatum, first in the baseline condition and again after methylphenidate challenge at a therapeutic dose for ADHD (0.3 mg/kg, p.o.) in order to map the altered dopamine release evoked by the psychostimulant challenge. Neuropsychological measurements of impulsivity and inattention were also performed. We found a positive correlation between commission errors and the methylphenidate-evoked decrease in [(11)C]raclopride binding, thought to reflect the balance of dopamine release and reuptake. The greater the decline in the [(11)C]raclopride binding, the greater the ability of methylphenidate to block the reuptake of dopamine. As the ability to block the reuptake depends on the relative dopamine concentration, the result suggests that the impulsivity in these adolescents is associated with abnormally low extracellular dopamine concentration.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Clinical doses of methylphenidate in adults and adolescents increased extrasynaptic levels of dopamine in the striatum due to potent blockade of dopamine transporters.

    “Studies using positron emission tomography show that clinical doses of methylphenidate in adults (Volkow et al., 2002) and adolescents (Neto et al., 2002) increased (rather than decreased, as proposed by some theories) extrasynaptic levels of dopamine in the striatum due to potent blockade of dopamine transporters”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
