Neurofibromatosis

Neurofibromatosis

NF1

NF2/ NF2-related schwannomatosis
AKA: MISME (multiple inherited schwannomas, meningiomas, and ependymomas)

Definition
AD characterized by multiple CNS tumors

History
1992 Manchester criteria
2017 Revised Manchester
2022 NF2-related schwannomatosis

Pathophys
-22q12.2→ Merlin (tumor supressor gene)
>cytoskeletal and contact-dependent
-Schawannomas→ Antoni A & B
A→ dense (Verocay bodies)
B→ loose

Incidence
1 in 40,000 births

Dx
-NF2-SWN 2022
-Manchester
DDx
-Schwannomatosis→ only peripheral, no central

Management
-If found NF2:
>Annually eval→ bMRI, ophthal, audiologic
>Every 2y→ spine-MRI 
-If tumor present, more freq
-Therapies
>Bevacizumab→ good VS, poor meningioma; SAEs in 10% (HTN, thromboembolic)
>Brigatinib→ good VS and meningioma

Post-concussion syndrome

Post-concussion syndrome

Definition
mTBI ✚ persistent sx  fx impact  exclusion

mTBI
Head trauma with ± brief loss of consciousness (<30 min)
•± post‑traumatic amnesia (<24 h)
•± confusion/disorientation
•GCS 13–15
•No structural brain injury explaining symptoms

Persistent sx
•One or more post‑concussive sx
•Persisting beyond expected recovery
>4 weeks (children/adolescents)
>3 months (adults)

Sx domains
-Somatic: headache, dizziness, fatigue, photophobia/phonophobia
-Cognitive: attention deficit, memory impairment, slowed processing, executive dysfunction
-Emotional/Behavioral: irritability, anxiety, depression, emotional lability
-Sleep: insomnia, hypersomnia, fragmented sleep

Cannabis use disorder

Cannabis use disorder (CUD)

Note
-DSM-V criteria for CUD
-RCVS

Cannabis withdrawal syndrome
>not life-threatening, but can last 2 wks

Treatment
-Psychosocial tx (CBT) 

-OFF-label
>Acetylcysteine (NAC 1200 mg BID)
>Gabapentin
>Mirtazapine
>Dronabinol/nabiximols

Increase Alertness

Increase Alertness
Situations
-Stroke (mainly thalamic)
-PD/ MS
-Consciousness disorder (TBI)
-Narcolepsy/ OSA residual sleepiness

Medications
Base on safety

In-hospital
1st: caffeine, amantadine
2nd: methylphenidate
3rd: levodopa

Outpatient: 
-modafinil/ armodafinil, bupropion, atomoxetine
-dextroamphetamine, lisdexamfetamine

Unclear:
-solriamfetol, pitolisant
Safety pearls
-Avoid late‑day dosing → insomnia, agitation
-Monitor BP/HR with methylphenidate, amphetamines, solriamfetol
-Renal adjust amantadine
-Modafinil induces CYP3A4 → ↓ OCP effectiveness
-Start low and titrate weekly
