Possible Diagnoses

• Thrombotic thrombocytopenic purpura (TTP) is a likely diagnosis given the symptoms of thrombocytopenia, altered sensorium, and vision loss. Other possibilities include central nervous system infections or hematologic emergencies.

Diagnostic Approach

• Key investigations include complete blood count, peripheral smear, coagulation profile, renal function tests, brain imaging (CT/MRI), and ADAMTS13 activity testing for TTP.

Treatment Options

• Immediate plasma exchange is critical for TTP. Supportive care and addressing underlying causes are essential. Corticosteroids and immunosuppressants may be used based on the specific diagnosis.

Specialist Referral and Monitoring

• Urgent consultation with hematology and neurology specialists is necessary. Continuous monitoring of neurological status and platelet counts is crucial.

Patient and Caregiver Guidance

• Advise on recognizing worsening symptoms and the importance of seeking immediate medical attention if conditions deteriorate.
