PSP Diagnosis? Progressive Supranuclear Palsy (Medical Condition)

PSP stands for Progressive Supranuclear Palsy — a rare neurodegenerative brain disorder. It is not a PlayStation Portable diagnosis.

Clinical Diagnosis of PSP (Medical)

No single test confirms PSP. Diagnosis is clinical, based on:

• Core Features (NINDS-SPSP Criteria):
  • Vertical Supranuclear Gaze Palsy: Inability to look down/up voluntarily (slow saccades). Hallmark sign.
  • Postural Instability / Falls: Early (within 3 years), backward falls, stiff gait.
  • Parkinsonism: Axial rigidity > limb, poor levodopa response.
  • Cognitive/Behavioral: Executive dysfunction, apathy, disinhibition, frontal lobe signs.
• Supportive Imaging:
  • MRI: "Hummingbird Sign" / "Penguin Sign" — Midbrain atrophy (selective), preserved pons. 3rd ventricle dilation.
  • DaTscan / PET: Reduced dopaminergic uptake (striatum).
• Exclusion: Rule out Parkinson's (PD), MSA, CBD, Vascular, NPH, Drug-induced.

Probable vs Possible PSP

• Probable: Vertical gaze palsy + Postural instability (falls in 3 yrs).
• Possible: One core + supportive imaging/exclusion.

If You Meant PlayStation Portable (Console) Troubleshooting

• Won't Turn On: Battery dead, charger port broken, power board fuse (F1/F2), motherboard short.
• Screen Issues: Backlight (inverter/LED), Ribbon cable, LCD panel.
• UMD Drive: Laser dead, motor, spindle, door sensor.
• Buttons/Analog: Membrane wear, drift (clean/replace).
• Brick (Semi/Full): Bad flash (CFW install fail). Recovery: Pandora Battery + MMS (Phat/1000/2000 only), JTAG (3000/Go/Street).

For medical PSP: See a Neurologist (Movement Disorders specialist). For console PSP: Describe symptoms (model, LED behavior, screen, sounds) for repair guidance.
