Diagnostic Plan for 9-Year-Old Female with Hand Shaking, ADHD Symptoms, and Social Anxiety

Immediate Priority: Rule Out Metabolic Emergency

This patient requires urgent medical evaluation for diabetes mellitus before any psychiatric treatment is initiated. The constellation of episodic hand shaking with hunger, increased thirst, increased appetite despite prolonged meal times, and strong family history of type 2 diabetes mandates immediate metabolic workup 1.

Required Urgent Laboratory Testing

Fasting plasma glucose (diabetes diagnosed if ≥126 mg/dL) 1
Hemoglobin A1c (diabetes diagnosed if ≥6.5%) 1
Random glucose if symptomatic hypoglycemia suspected
Thyroid function tests given paternal family history of hyperthyroidism
Complete metabolic panel to assess kidney function and electrolytes

Clinical reasoning: Family history of type 2 diabetes increases risk substantially, with earlier disease onset and higher cardiovascular risk in familial diabetes 2, 3. The hand shaking episodes that resolve with food intake, combined with polydipsia and polyphagia, represent classic warning signs that cannot be attributed to psychiatric causes alone. The fact that episodes occur even after breakfast suggests inadequate glucose regulation rather than simple hunger.

Comprehensive ADHD Diagnostic Evaluation

Confirm DSM-5 Diagnostic Criteria

The psychometric assessment data already demonstrates that ADHD Combined Presentation criteria are met (98.2nd percentile on SWAN scale, elevated on both inattention and hyperactivity/impulsivity subscales) 4. However, formal documentation requires:

Multi-Setting Verification (Mandatory)

Obtain standardized rating scales from at least 2 teachers to document cross-setting impairment 4
Document specific functional impairment in both home and school settings (already partially completed through parent report and teacher observation) 4
Verify symptom onset before age 12 (appears met given "longstanding attention difficulties" and early childhood self-stimulating behaviors) 4

Symptom Documentation Already Completed

Inattention domain: 5 symptoms rated Below Average or Far Below Average (fails to give close attention, difficulty sustaining attention, doesn't follow through, avoids sustained mental effort, loses things) 4
Hyperactivity-Impulsivity domain: 5 symptoms rated Below Average or Slightly Below Average (fidgets, leaves seat, talks excessively, difficulty waiting turn, interrupts) 4

Mandatory Comorbidity Screening

The American Academy of Pediatrics requires screening for comorbid conditions in all children evaluated for ADHD 4. This patient's presentation demands particular attention to:

Psychiatric Comorbidities to Evaluate

Social Anxiety Disorder (Already Identified)

RCADS score at 96.5th percentile for Social Phobia confirms elevated symptoms requiring treatment 4
Functional impairment documented: reluctance to use finger counting due to peer judgment concerns
Treatment implications: Social anxiety may alter ADHD treatment sequencing 4

Depressive Symptoms (Requires Monitoring)

RCADS score at 91st percentile for Major Depression indicates mild range requiring close monitoring 4
Self-critical thoughts and self-punishment through negative self-talk ("I should be ashamed") warrant ongoing assessment
Critical distinction: These symptoms appear related to perfectionism and academic frustration rather than primary mood disorder, but require serial monitoring 4

Trauma and Toxic Stress (Must Rule Out)

Screen specifically for trauma exposure, PTSD, and toxic stress as these are additional comorbidities of concern that can mimic ADHD 4, 5
PTSD can manifest with impulsivity, hyperarousal, and attention difficulties that closely mimic ADHD symptoms 5
Ask directly about: traumatic experiences, abuse, neglect, household dysfunction, exposure to violence
If positive screening: Refer to trauma-informed mental health specialist before initiating ADHD treatment 5

Autism Spectrum Disorder Evaluation

The AQ score at 94.9th percentile (below diagnostic threshold but elevated) combined with clinical features requires careful consideration 4:

Attention Switching subscale: 98.3rd percentile (preference for predictability, stress with unexpected changes)
Attention to Detail subscale: 97.3rd percentile (heightened focus on details/patterns)
Self-stimulating behaviors since early childhood (repetitive hand movements)
Environmental rigidity (specific table arrangement requirements, distress when items out of place)

Clinical decision: While full ASD criteria are not met, these features may represent subclinical autism traits that will influence treatment approach 4. The social difficulties appear more consistent with social anxiety than the persistent social communication deficits characteristic of autism 4.

Learning and Language Disorders

Comprehensive educational evaluation for IEP or 504 plan development (already recommended) 4
Specific assessment for: reading disorders, mathematics disorders, written expression disorders, language processing disorders 4
Rationale: Learning disabilities commonly present with inattention and behavioral dysregulation that appears impulsive 5

Sleep Disorders

Screen for sleep apnea and other sleep disorders that produce daytime hyperactivity, inattention, and impulsive behavior 4
Ask about: snoring, witnessed apneas, restless sleep, daytime sleepiness, difficulty waking
If positive screening: Refer for polysomnography before attributing all symptoms to ADHD 5

Differential Diagnosis Considerations

Conditions That Must Be Ruled Out

The American Academy of Pediatrics emphasizes ruling out alternative causes before finalizing ADHD diagnosis 4:

Metabolic/Endocrine Conditions (Highest Priority)

Diabetes mellitus (as discussed above - urgent evaluation required)
Hyperthyroidism (given paternal family history) - can cause hyperactivity, anxiety, difficulty concentrating
Hypoglycemia (given paternal family history of "low blood sugar episodes")

Substance Use (Lower Priority Given Age)

While less likely at age 9, must be considered given that substance use can mimic ADHD symptoms 4, 5
Marijuana and other substances can produce inattention and impulsivity 5

Seizure Disorders

Absence seizures can mimic inattention 5
The history of febrile seizure warrants consideration, though unlikely given symptom pattern

Diagnostic Algorithm Summary

Step 1: Urgent Medical Evaluation (Within 48-72 Hours)

Fasting glucose, HbA1c, thyroid function tests, comprehensive metabolic panel 1
If diabetes confirmed: Immediate endocrinology referral and diabetes management initiation
If hypoglycemia documented: Endocrinology evaluation for underlying cause

Step 2: Complete ADHD Documentation (Within 2 Weeks)

Obtain standardized rating scales from minimum 2 teachers 4
Document cross-setting impairment with specific functional examples 4
Verify symptom onset before age 12 through detailed developmental history 4

Step 3: Systematic Comorbidity Screening (Within 2 Weeks)

Trauma screening: Direct questions about traumatic experiences, PTSD symptoms 4, 5
Sleep disorder screening: Questions about sleep quality, snoring, daytime sleepiness 4, 5
Learning disability assessment: Comprehensive educational evaluation for IEP/504 4
Mood monitoring: Serial assessment of depressive symptoms given 91st percentile score 4

Step 4: Subspecialty Referrals as Indicated

Endocrinology: If metabolic abnormalities identified (highest priority)
Trauma-informed mental health specialist: If positive trauma screening 5
Sleep medicine: If positive sleep disorder screening 5
Educational psychologist: For comprehensive learning assessment 4

Critical Diagnostic Pitfalls to Avoid

Common errors that lead to misdiagnosis and inappropriate treatment 5:

Failing to obtain multi-setting documentation before concluding ADHD criteria are met - this patient needs teacher rating scales from at least 2 teachers 4
Missing metabolic causes of symptoms - the hand shaking with hunger and family history of diabetes cannot be ignored 1
Assigning ADHD diagnosis when symptoms are better explained by trauma - must actively screen for trauma exposure 5
Not establishing symptom onset before age 12 - while this appears met, formal documentation is required 4
Relying solely on parent reports without corroborating information from multiple sources 5
Overlooking sleep disorders that produce identical symptom patterns 5

Treatment Sequencing Based on Diagnostic Findings

If Diabetes/Metabolic Disorder Confirmed

Metabolic stabilization takes absolute priority before psychiatric treatment 1
ADHD treatment can proceed concurrently once metabolic condition is being managed, but requires close coordination 6
Monitor for interaction effects: ADHD symptoms and poor executive function can negatively impact diabetes management 6, 7

If ADHD Confirmed Without Metabolic Disorder

For age 9 (elementary school-aged): FDA-approved ADHD medications AND parent training in behavior management AND behavioral classroom interventions (preferably all three) 4, 8
Social anxiety requires concurrent treatment: Cognitive-behavioral therapy specifically targeting social anxiety and self-critical thoughts 4
Educational accommodations: IEP or 504 plan with specific supports for attention difficulties 4

If Trauma/PTSD Identified

Trauma-focused treatment takes priority before ADHD-specific interventions 5
Behavioral interventions remain beneficial and do not require specific diagnosis 5, 8

Follow-Up Timeline

2-4 weeks: Review medical evaluation results and determine treatment sequencing 4
Monthly initially: Monitor treatment response, side effects, and comorbid symptoms 4
Ongoing: ADHD is a chronic condition requiring long-term management following chronic care model principles 4, 9
