Some physical tests
The following test helps them check for imbalances in a person’s brain chemistry and electrolyte levels and verify the presence of any medical conditions:
- Blood test
- Urine test
- ESR
- CBC
- X-ray skull
- CT scan of the skul
- MRI of the skull
- Electroencephalography
- Brain biopsy
- Thyroid test
Management
- Identification of cause and its immediate correction is the primary goal of treatment. Medications can be given according to the cause of the disease. With that, supportive care should be given, which includes the following.
- Encouraging family members or familiar people for involvement.
- Supportive care/nonpharmacological intervention:
Supportive care aims to prevent complications by:
