Brother: “ Want to get Neuropsychiatric evaluation for insurance claim” HISTORY OF PRESENT ILLNESS Patient is known case of Intelligent disability, moderate. The patient is an adopted female who was brought for psychiatric evaluation due to longstanding cognitive and adaptive functioning difficulties. According to her caregiver, developmental concerns became evident during early childhood. Her cognitive limitations continue to affect her daily functioning. She is unable to go to the market independently, manage money, or perform more complex household tasks. The patient prefers routines and becomes anxious or upset when promises made to her are not fulfilled. She was brought for consultation because she requires a government-certified neuropsychiatric evaluation stating her illness to support her insurance claim for financial assistance with her living expenses. Her brother accompanied her to the Vicente Sotto Memorial Medical Center – Center for Behavioral Sciences Outpatient Department (VSMMC-CBS OPD) for her first consultation on July 15, 2026. PAST PSYCHIATRIC HISTORY The Patient at the age of 7 she had her psychiatric consult for delayed cognitive development. She had noticed to have IQ of 3 year old at the age of 7. No Psychotropic medications had been taken. Patient had no history of suicidal or homicidal thoughts process in the past. SUBSTANCE USE/ ABUSE HISTORY Patient is non smoker, non alcoholic beverage drinker and no history of any known illicit drug. No abuse or bullying has been noted. No history of suicidal/homicidal thought noted. PAST MEDICAL HISTORY Patients denied previous Hospitalization or surgeries. The patient denied any chronic illness or taking maintenance medication. The patient has no hypertension, diabetes mellitus, bronchial asthma, thyroid or cancer issues. No drug or food allergies noted. FAMILY HISTORY The patient is the adopted daughter of her current parents. She has three biological siblings, who are also reported to have psychiatric or developmental conditions. She has four adopted brothers. Her family has not disclosed to her that she is adopted. Her biological parents are relatives of her adoptive family. The patient currently lives with her adoptive mother, her eldest brother, his wife, and their two children. Her adoptive father died in 2026 due to liver cirrhosis. According to her brother, the patient has a good relationship with all family members. A family history of hypertension and diabetes mellitus is present. DEVELOPMENTAL AND SOCIAL HISTORY Prenatal, Natal, and Postnatal History: Since the patient had been adopted her brother doesn't knew the mode of delivery and other parts of prenatal, natal and postnatal history. Early Childhood (0–3 years): The Primary Care giver for the patient was his mother. She had been adopted at the age of 3 months old. As all her adopted siblings are boys. The brother claims that she had been given formula milk. All her developmental milestones were on par started walking at the age of 3, could able to ride tricycle but had difficulty in speech. Middle Childhood (3–11 years): Her mother is the primary care taker. She started speaking at the age 4( like Mama, Papa). She was enrolled in Regular nursery academy Guimaras province. There she had been noticed to be different from other children. Always she requires additional care from the teachers. And had difficulty in learning and coping up with her grades. At the age of 9, the patient had stopped from going school. Later entrolled in SPED schools. Started writing at the age of 6. Brother claims that the patient get aggressive whenever she gets angry or if they forget to do what they had promised. Later childhood to Adulthood During her SPED schooling days, Patient had learnt how to cook ( boiling egg), painting and coloring she is good at this. She had her 1st menstrual period at the age of 13, patient had difficulty in changing in her napkins not knowing what is happening to her body. Later she had been taught by her mother slowing later she can able to do. She has difficulty in taking complex things to her mind. She couldn't go to store and get proper change.

She could understand his absence amd cause of death MENTAL STATUS EXAMINATION The patient is awake, alert, and cooperative throughout the interview. She is fairly groomed and dressed appropriately for her age. She maintains good eye contact. Her speech is slow, with decreased fluency and unclear articulation at times, but is relevant and coherent. She is aware of her surroundings and is oriented to person, place, but not time.Her mood is euthymic with a congruent and appropriate affect. There is no evidence of auditory or visual hallucinations, delusions, or other perceptual disturbances. Thought process is generally goal-directed but concrete, with no loosening of associations or flight of ideas. Thought content is unremarkable, with no suicidal or homicidal ideation. Attention and concentration are impaired. She is able to spell "DOG" forward but is unable to spell it backward. Immediate memory is intact, while recent and remote memory are grossly intact. Fund of knowledge is below that expected for her chronological age. She demonstrates impaired calculation, as she is unable to perform simple subtraction. Abstract thinking is impaired, and her responses are predominantly concrete. Judgment is impaired in practical situations, particularly regarding money management and independent activities of daily living. Insight is poor.

I now have sufficient information from Kaplan & Sadock's to construct a thorough, well-sourced answer. Let me compile it.

Differential Diagnosis - 3 Best Differentials per DSM-5-TR

Based on the clinical presentation, the primary impression of Intellectual Disability (ID), Moderate is strongly supported. Below are the 3 best differential diagnoses, with detailed rule-in and rule-out reasoning.

Primary Impression: Intellectual Disability (ID), Moderate

(F71 - DSM-5-TR)
DSM-5-TR requires all three:
  1. Deficits in intellectual functioning (reasoning, problem-solving, abstract thinking, learning)
  2. Deficits in adaptive functioning in at least one of three domains (conceptual, social, practical) that necessitates support
  3. Onset during the developmental period (before age 18)
This patient meets all three criteria:
  • Cognitive deficits present since early childhood (IQ approximated at 3-year-old level at age 7)
  • Adaptive deficits: cannot manage money, shop independently, or comprehend her own menstrual hygiene without teaching
  • Onset well before age 18, per history
Severity is Moderate based on adaptive functioning profile consistent with the table in Kaplan & Sadock's Synopsis: she can communicate, perform basic self-care when taught, profit from SPED training (cooking, painting), but cannot manage academic work beyond early primary level, cannot handle monetary transactions, and requires supervision in community settings.

Differential Diagnosis 1: Autism Spectrum Disorder (ASD)

(F84.0 - DSM-5-TR)

DSM-5-TR Criteria Overview

ASD requires:
  • Persistent deficits in social communication and social interaction across multiple contexts
  • Restricted, repetitive patterns of behavior, interests, or activities (RRBs)
  • Symptoms present in the early developmental period
  • Clinically significant impairment
  • Not better explained by ID alone (though both can co-occur; if comorbid, social communication must be below that expected for general developmental level)

Rule-In Features (present in this patient)

FeatureEvidence from Case
Social deficitsHas no friends, highly isolated socially
Rigidity/routine insistence"Becomes anxious or upset when promises made to her are not fulfilled" - suggests need for predictability and routine
Restricted/repetitive interestsIntense focus on KPOP singing and Zumba, heavy YouTube use
Speech and language delayDid not speak until age 4; slow, decreased fluency with unclear articulation
Developmental onsetNoted in early childhood
Concrete thinkingDemonstrated throughout MSE

Rule-Out Features (not present / not documented)

FeatureEvidence from Case
Stereotyped/repetitive motor movementsNo hand-flapping, rocking, or motor mannerisms documented
Sensory hypersensitivity/hyposensitivityNot reported by caregiver or observed
Social communication below developmental levelHer social warmth and good eye contact suggest social communication that is broadly consistent with her cognitive level - a key DSM-5 distinction. Per Kaplan & Sadock's: "children with intellectual disability typically demonstrate social and emotional development that is relatively consistent with their cognitive functioning"
Pronoun reversal, echolalia, or atypical pragmatic languageNot documented
Attachment difficulties or indiscriminate social behaviorShe shows appropriate attachment to family and was described as having good relationships

Conclusion

ASD is a meaningful differential but is ruled out as a primary diagnosis. The aggression with broken promises and her interest fixation raise suspicion, but the absence of classic RRBs (motor stereotypies, sensory issues) and the fact that her social-emotional behavior appears consistent with her cognitive developmental level (not below it) argues against ASD as a primary diagnosis. It remains a comorbidity to investigate formally with a structured instrument (e.g., ADOS-2).
Source: Kaplan & Sadock's Comprehensive Textbook of Psychiatry - "Intellectual disability and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of ASD and ID, social communication should be below that expected for general developmental level."

Differential Diagnosis 2: Borderline Intellectual Functioning (BIF)

(R41.83 - DSM-5-TR)

DSM-5-TR Definition

BIF is categorized under "Other Conditions That May Be a Focus of Clinical Attention." It refers to an IQ typically in the range of 71-84 (well below average, 1-2 SDs below mean), where adaptive functioning deficits are present but do not meet full criteria for ID. DSM-5-TR requires careful assessment of both intellectual and adaptive functions and their discrepancies.

Rule-In Features

FeatureEvidence from Case
Global learning difficultiesStruggled in regular school, required extra teacher attention
Concrete thinkingPresent on MSE
Impaired judgment and abstractionCannot manage money, perform complex household tasks, or manage menstruation without teaching
Below-expected fund of knowledgeDocumented on MSE
Difficulty with complex tasksCannot add two-digit numbers, cannot give change

Rule-Out Features

FeatureEvidence from Case
IQ at age 7 approximated at 3-year-old levelThis places her well below the IQ 71-84 BIF range - this level of cognitive functioning is more consistent with moderate ID (IQ ~35-49 by ICD-10 standards)
Adaptive functioning severityHer deficits are extensive across all three adaptive domains (conceptual: math at single-digit level; social: no friendships, poor insight; practical: cannot shop, cannot independently manage menstruation without instruction)
Onset and severityThe severity and lifelong developmental course exceeds what BIF alone would produce

Conclusion

BIF is ruled out. Her childhood IQ approximation, the breadth of her adaptive deficits across all three domains (conceptual, social, practical), and her dependence on others for community activities all exceed the mild impairment profile expected in BIF. As noted in Kaplan & Sadock's Comprehensive Textbook: "Differentiating BIF and mild ID requires careful assessment of intellectual and adaptive functions and their discrepancies." In this patient, both intellectual and adaptive functioning are substantially, not merely "well below average," impaired - consistent with Moderate ID, not BIF.

Differential Diagnosis 3: Autism Spectrum Disorder with Accompanying Intellectual Impairment vs. Intellectual Disability Alone

(Reconsidered as: Specific Learning Disorder or Communication Disorder)
A more clinically useful third differential in this particular case is a Communication Disorder (Language Disorder, F80.9) presenting with secondary cognitive-adaptive impairment, OR alternatively framed as a Specific Learning Disorder being mistaken for global intellectual impairment.

Option A: Language Disorder (DSM-5-TR F80.9)

DSM-5-TR Criteria Overview

  • Persistent difficulties in acquisition and use of language across modalities (spoken, written, sign) due to deficits in comprehension or production
  • Language abilities substantially and quantifiably below those expected for age
  • Onset in the early developmental period
  • Not attributable to hearing or other sensory impairment, motor dysfunction, or another medical/neurological condition, and not better explained by ID or global developmental delay

Rule-In Features

FeatureEvidence
Delayed speech onsetFirst words ("Mama, Papa") at age 4
Decreased fluency and unclear articulationDocumented on MSE
Slow speechDocumented on MSE
Difficulty with complex informationExplicit in history

Rule-Out Features

FeatureEvidence
Global cognitive impairment, not language-specificHer deficits span conceptual (math), social (no friends, poor insight), and practical (money, hygiene) domains - this is not limited to communication
DSM-5-TR explicitly excludes IDLanguage disorder is NOT diagnosed if better explained by ID
Fund of knowledge impairedGlobal, not restricted to language
Abstract reasoning impairedConcrete thinking across all domains

Conclusion

Language disorder as a standalone diagnosis is ruled out. Her impairments are global across all three adaptive domains, not restricted to language. Language difficulties in this case are a feature of her underlying Moderate ID, not a separate primary condition. Per Kaplan & Sadock's Synopsis differential diagnosis section, language disorder and ID can co-occur but the broader global cognitive picture here points to ID as primary.

Summary Table

DifferentialKey Rule-In FeaturesKey Rule-Out FeaturesFinal Status
Autism Spectrum DisorderNo friends, routine rigidity, restricted interests (KPOP/Zumba), speech delayNo motor stereotypies, no sensory issues, social-emotional level consistent with cognitive level, good eye contact, appropriate attachmentRuled out as primary; consider formal ASD screening for comorbidity
Borderline Intellectual FunctioningConcrete thinking, below-expected knowledge, judgment impairmentIQ approximated well below BIF range at age 7; broad multi-domain adaptive deficits far exceed BIF profileRuled out
Language DisorderDelayed first words, slow/decreased fluency, unclear articulationDeficits are global (math, social, practical) - not language-specific; DSM-5-TR excludes if better explained by IDRuled out

Clinical Note for the Neuropsychiatric Evaluation

To formally confirm Intellectual Disability, Moderate and definitively exclude the differentials above, the evaluating psychiatrist should document:
  1. Standardized IQ testing - e.g., WAIS-IV or WISC-V (or equivalent culturally-appropriate instrument in Filipino Cebuano-speaking population)
  2. Adaptive behavior scale - e.g., Vineland Adaptive Behavior Scales, 3rd Edition (Vineland-3), covering communication, daily living skills, socialization
  3. Screening for ASD - a structured instrument such as ADOS-2 or SCQ to exclude comorbid ASD, given the routine rigidity and social isolation
  4. Documentation of developmental onset (confirmed - onset before age 18, per history since infancy)
  5. Exclusion of medical causes - thyroid function, metabolic panel (already partially done with no chronic illness history)
