Cerebral malaria, a severe complication caused by Plasmodium falciparum, can quickly escalate from a mosquito bite to a life-threatening brain emergency. Firstpost brings out an expert’s view on how the parasite invades the brain, the early warning signs like seizures and coma and why rapid diagnosis and intensive treatment are crucial to prevent permanent neurological damage or death.read moreCerebral
Malaria is a severe neurological condition caused by the malaria parasite Plasmodium falciparum, which is transmitted through the bites of infected Anopheles mosquitoes. This form of malaria affects the brain, leading to various serious symptoms and complications.Firstpost talked to inputs by Dr Anurag Aggarwal, Consultant, Internal Medicine, Fortis Escorts Hospital (Faridabad) to know how it develops, its warning signs, diagnostic methods, treatment options and the urgent need for preventive measures.STORY CONTINUES BELOW THIS ADWorld Malaria Day: Why India’s fight against malaria requires more than just medicineCauses and transmissionCerebral Malaria is primarily caused by the parasite Plasmodium falciparum. When an infected mosquito bites a human, the parasites travel to the liver, where they multiply before invading red blood cells. As the parasites continue to reproduce, they cause the red blood cells to become sticky and clump together, blocking the small blood vessels in the brain. This obstruction reduces blood flow and leads to brain swelling, which is the hallmark of cerebral malaria.SymptomsThe symptoms of cerebral malaria can appear as early as 7 days after exposure. They include:- Severe Headache: Initially, patients may experience intense headaches.- High Fever: A high and recurrent fever is one of the primary signs.More from Health

Trump’s draft order proposes radical overhaul of State Department and foreign diplomacy- Seizures: Convulsions or seizures may occur due to the brain’s involvement.- Coma: In severe cases, patients can fall into a coma, a critical condition that requires urgent medical attention.- Neurological Deficits: Symptoms like confusion, behavioral changes, and impaired movement can occur.Accompanying these core symptoms, patients might also experience nausea, vomiting, and general malaise. Due to its ability to swiftly progress to severe illness, early detection and treatment are crucial.DiagnosisDiagnosing cerebral malaria involves a combination of clinical evaluation and laboratory tests. Blood smears can reveal the presence of parasites, while rapid diagnostic tests identify specific malaria antigens. MRI and CT scans can detect brain swelling, and other neurological assessments may be performed to gauge the level of brain involvement.TreatmentImmediate, aggressive treatment is essential to combat cerebral malaria. The main line of treatment is intravenous antimalarial drugs, such as artesunate or quinine. Supportive care, including managing seizures and maintaining adequate oxygen levels, is critical. Patients may require intensive care support due to the severe complications that can develop.PreventionPreventive measures are vital, especially in malaria-endemic regions:- Insecticide-Treated Bed Nets: Sleeping under treated nets can significantly reduce mosquito bites.- Preventive Antimalarial Drugs: Prophylactic medication is recommended for travellers to high-risk areas.- Indoor Residual Spraying: Applying insecticides indoors can prevent mosquito breeding.- Protective Clothing and Repellents: Wearing long sleeves and using mosquito repellents can lower the risk.Prognosis and complicationsWith timely and appropriate treatment, the prognosis for cerebral malaria can be good; however, delays can lead to severe complications, including irreversible brain damage or death. Children and pregnant women are particularly vulnerable to the worst outcomes.Cerebral Malaria is a severe and potentially fatal condition that requires immediate attention and treatment. Its prevalence in sub-Saharan Africa and parts of Asia and Latin America necessitates robust preventive measures and awareness to reduce transmission. Understanding its symptoms, diagnosis, and treatment options is crucial for both individuals residing in and traveling to endemic areas.STORY CONTINUES BELOW THIS ADEducating communities and improving access to healthcare can help mitigate the impact of cerebral malaria, ultimately saving lives and improving health outcomes in affected regions.TagsHealthEnd of Article
