• Transverse myelitis
• Acute disseminated encephalomyelitis (ADEM)
• Optic neuritis
• Multiple sclerosis

  Correct answer: Acute disseminated encephalomyelitis (ADEM)   Explanation: Acute disseminated encephalomyelitis (ADEM) is a monophasic, immune-mediated, inflammatory demyelinating disease of the central nervous system (CNS) that typically occurs after a viral infection or vaccination, especially in children and young adults. Key features of ADEM:

• Monophasic (single episode, not relapsing)
• Widespread CNS demyelination
• Often follows a preceding infection or immunization
• Symptoms: encephalopathy, seizures, motor/sensory deficits, ataxia, etc.
• MRI shows diffuse, bilateral, asymmetric white matter lesions

  Why the other options are incorrect:

• Transverse myelitis → Inflammation of the spinal cord, may occur as part of a monophasic or multiphasic disorder, but not disseminated across the CNS
• Optic neuritis → Inflammation of the optic nerve; typically focal, and often associated with multiple sclerosis
• Multiple sclerosis (MS) → Chronic, relapsing-remitting or progressive, disseminated CNS disorder — not monophasic
