Succinic Semialdehyde Dehydrogenase Deficiency Severity

Evaluates succinic semialdehyde dehydrogenase (SSADH) deficiency severity using CSF and urine 4-hydroxybutyric acid (GHB), EEG abnormalities, and neuropsychiatric features to guide vigabatrin response assessment.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Evaluates succinic semialdehyde dehydrogenase (SSADH) deficiency severity using CSF and urine 4-hydroxybutyric acid (GHB), EEG abnormalities, and neuropsychiatric features to guide vigabatrin response assessment

Each component has a specific meaning:

  • CSF — The csf recorded for the scenario being assessed.
  • Urine 4-hydroxybutyric acid — The urine 4-hydroxybutyric acid recorded for the scenario being assessed.
  • EEG abnormalities — The eeg abnormalities recorded for the scenario being assessed.
  • Neuropsychiatric features — The neuropsychiatric features recorded for the scenario being assessed.

Note: Interpret the ssadh deficiency result against the thresholds and context described above.

How to Use

Enter the CSF, urine 4-hydroxybutyric acid, EEG abnormalities, neuropsychiatric features for the scenario you are assessing. Evaluates succinic semialdehyde dehydrogenase (SSADH) deficiency severity using CSF and urine 4-hydroxybutyric acid (GHB), EEG abnormalities, and neuropsychiatric features to guide vigabatrin response assessment. Use the ssadh deficiency result to inform your calculation.
