Quick Answer
Monsoon brings malaria, dengue, encephalitis and fungal infections — several affect the nervous system. Here's how to protect yourself during Nepal's rainy season.

Nepal's monsoon (June–September) transforms the country — flooding, waterlogging, increased vector populations and humidity create conditions for diseases that directly or indirectly affect neurological health. Several monsoon-related infections can cause encephalitis, meningitis and neuropathy.
Infections that affect the nervous system during monsoon
Japanese encephalitis: mosquito-borne viral encephalitis — causes fever, headache, seizures, coma. Endemic in Nepal's Terai; vaccination available.,Meningitis: bacterial or viral inflammation of brain membranes — causes severe headache, neck stiffness, fever, confusion. Monsoon increases risk.,Malaria: Plasmodium falciparum can cause cerebral malaria — fever with confusion, seizures, coma. Requires urgent treatment.,Dengue: usually not neurological but severe dengue can cause encephalopathy.,Leptospirosis: water-borne bacterial infection — can cause meningitis-like symptoms.
Fungal and water-related risks
Flooding and waterlogging increase exposure to fungi (aspergillosis, mucormycosis — especially in diabetics and immunocompromised) and water-borne pathogens. Avoid walking through floodwater, especially with open wounds. Skin and eye infections increase — keep wounds clean and dry.
Practical monsoon precautions
Mosquito protection: bed nets, repellent, covering exposed skin — especially at dawn/dusk.,Clean water: drink boiled or filtered water — monsoon contaminates water sources.,Food safety: avoid street food during monsoon — food poisoning weakens immunity.,Foot care: dry feet thoroughly — fungal infections thrive in damp conditions (especially important for diabetics with neuropathy).,Vaccination: ensure Japanese encephalitis vaccination if living in or traveling to endemic areas.,Prompt care: fever with headache, neck stiffness, confusion or seizures during monsoon — seek urgent evaluation.
Neurological red flags during monsoon
Fever with severe headache and neck stiffness (meningitis), fever with confusion or seizures (encephalitis), fever with altered consciousness (cerebral malaria), or any neurological symptom after flood exposure — seek urgent medical care. These conditions are time-sensitive.
When to seek professional evaluation
Monsoon-related neurological symptoms — fever with headache, neck stiffness, confusion or seizures — need urgent evaluation. Contact Kathmandu Neurology Clinic for guidance.

Note time of onset, call emergency services, do not give food/drink or leave the person alone.
TIA symptoms resolve, but it signals high short-term stroke risk. Urgent evaluation and prevention planning are essential.
Not necessarily; a single unprovoked seizure needs careful assessment before a diagnosis of epilepsy is made.
No; seizures vary widely. Some involve jerking (generalized or focal), while others present as staring spells, automatisms, or behavioral change with no apparent movement.
