Late-diagnosed ADHD adult with high WAIS scores — possible 2e or just high intelligence?
Hello everyone,
I recently underwent a full neuropsychological evaluation because my psychiatrist suspected ADHD and possibly twice-exceptionality (2e), so he referred me to a neuropsychologist experienced in adult ADHD assessment.
The evaluation included:
- WAIS-IV
- Rey Complex Figure Test
- Executive functioning and ADHD-related scales/tests
The neuropsychologist diagnosed me with moderate combined ADHD, but stated that I do not meet criteria for giftedness / twice-exceptionality mainly because of a 16-point discrepancy between my VCI and PRI scores on the WAIS-IV.
According to her interpretation, this discrepancy would be inconsistent with a gifted cognitive profile. She used the metaphor of “a Ferrari engine trapped in a golf cart” to describe my functioning.
However, my psychiatrist disagrees with several aspects of the interpretation. He believes the context surrounding the testing was not sufficiently considered, especially:
- untreated ADHD at the time of testing,
- chronic anxiety history,
- and the fact that I have been treated with antidepressants for GAD for over 10 years.
Interestingly, the neuropsychologist concluded that I do not currently meet full criteria for GAD, although the testing still showed moderate anxiety traits. My psychiatrist argued that long-term treatment may have partially reduced the visible anxiety profile during testing.
At the moment, he is considering:
- ADHD,
- ADHD + giftedness / 2e,
- and anxiety as overlapping possibilities.
This divergence between professionals has honestly left me confused.
I’ve been reading extensively about ADHD, but I do not fully relate to many “classic” ADHD presentations.
Some personal traits/history that seem relevant:
- extremely talkative and mentally hyperactive since childhood,
- highly curious and investigative,
- tendency to hyperfocus deeply on topics of interest,
- difficulty letting go of unanswered questions or illogical explanations,
- tendency to overwhelm people unintentionally by going too deep into discussions,
- intense intellectual interests often perceived as “too much” or “weird” by others,
- very strong verbal/auditory memory,
- unusually easy language acquisition,
- adaptation to different cultures/languages,
- chronic feeling of being misunderstood socially,
- excellent academic performance with very little studying during childhood/adolescence,
- increasing executive dysfunction only becoming obvious in adulthood with higher life demands.
WAIS-IV results:
- FSIQ: 131
- VCI: 137
- PRI: 121
- WMI: 133
- PSI: 129
WAIS-IV subtests (raw scores):
- Vocabulary: 62

Executive functioning / ADHD-related tests:
BDEFS (Barkley Deficits in Executive Functioning Scale):
- Total Score: Percentile 90
- Time Management: Percentile 95
- Motivation: Percentile 90
- Organization / Problem Solving: Percentile 80
- Emotional Regulation: Percentile 80
- Self-Control: Percentile 60
- ADHD Symptoms Index: Percentile 95
- Dysexecutive Symptoms Index: Percentile 90
ADT (Time Management Inventory):
- 59 affirmative responses indicating significant executive functioning and time-management difficulties.
FDT (Five Digits Test):
- Reading: Percentile 75
- Counting: Percentile 50–75
- Choice / Inhibitory Control: Percentile 50–75
- Alternation / Cognitive Flexibility: Percentile 75–95
- Inhibition Index: Percentile 50–75
- Flexibility Index: Percentile 75–95
ETDAH-AD: Higher elevations in:
- Inattention
- Emotional aspects
- Self-regulation of attention/motivation/action
Lower elevation in:
- Impulsivity
Rey Complex Figure Test: The report described:
- organizational inefficiency,
- executive inconsistency,
- attentional fluctuation,
- and overload under complex/open-ended tasks.
I’m currently starting ADHD medication treatment and considering whether I should seek a second neuropsychological opinion about my tests' results.
I would genuinely appreciate hearing from people familiar with:
- gifted ADHD / 2e presentations,
- heterogeneous WAIS profiles,
- or adults diagnosed later in life.
Does this profile sound more consistent with:
- ADHD alone with high intelligence,
- or a possible twice-exceptional presentation?
