- Vision changes
Bell's Palsy
MildAn acute, idiopathic facial nerve palsy resulting in unilateral facial muscle weakness.
- Facial droop
- Inability to close eye
- Altered taste
Trigeminal Neuralgia
SevereA chronic pain condition affecting the trigeminal nerve, causing intense facial pain episodes.
- Sharp facial pain
- Trigger zones (e.g., chewing)
- Pain episodes lasting seconds to minutes
Huntington's Disease
ProgressiveAn autosomal dominant neurodegenerative disorder characterized by chorea, psychiatric symptoms, and cognitive decline.
- Involuntary movements
- Depression or irritability
- Memory loss
Cerebral Palsy
VariableA group of permanent movement disorders caused by brain injury or malformation during early development.
- Spasticity
- Ataxia
- Motor coordination deficits
Bacterial Meningitis
SevereAn acute inflammation of the meninges caused by bacterial infection, requiring urgent treatment.
- Fever
- Neck stiffness
- Photophobia
Viral Encephalitis
SevereInflammation of the brain parenchyma due to viral infection, leading to neurological deficits.
- Fever
- Headache
- Confusion
Multiple System Atrophy
ProgressiveA progressive neurodegenerative disorder with autonomic failure, parkinsonism, and cerebellar signs.
- Orthostatic hypotension
- Bradykinesia
- Ataxia
Charcot-Marie-Tooth Disease
VariableA hereditary peripheral neuropathy causing progressive loss of muscle tissue and touch sensation.
- Distal muscle weakness

- Sensory loss
Chronic Inflammatory Demyelinating Polyneuropathy
VariableAn immune-mediated neuropathy characterized by progressive weakness and impaired sensation in the limbs.
- Symmetric limb weakness
- Numbness
- Reduced reflexes
Restless Legs Syndrome
MildA sensorimotor disorder causing an irresistible urge to move the legs, especially at night.
- Leg discomfort
- Urge to move
- Worsening at rest
Narcolepsy
ModerateA chronic sleep disorder marked by excessive daytime sleepiness and sudden loss of muscle tone (cataplexy).
- Sudden sleep attacks
- Cataplexy

VariableA neurodevelopmental disorder characterized by multiple motor and at least one vocal tic persisting for >1 year.
- Motor tics
- Vocal tics
- Premonitory urges
Schizophrenia
VariableA chronic psychiatric disorder with profound disturbances in thought, perception, and behavior, linked to neurochemical dysregulation.

When to Seek Medical Help
For nervous conditions, consult a healthcare provider if you experience:
- Persistent or worsening symptoms
- Sudden onset of severe symptoms
- Symptoms that interfere with daily activities
- Signs of infection (fever, swelling, redness)
- Unexplained changes or new symptoms
