Living with Familial encephalopathy with neuroserpin inclusion bodies
A rare inherited brain condition with memory and thinking decline and seizures that are hard to control.
Understanding Familial encephalopathy with neuroserpin inclusion bodies
It causes loss of thinking skills (dementia) and seizures. Early signs may be problems with attention and concentration, followed by personality changes and memory trouble. People often need full-time care over time. Many have muscle-jerk seizures (myoclonus) that do not respond well to seizure medicine. Signs can appear at any age, from childhood to adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Dementia (loss of thinking skills)
- Seizures
- Muscle jerks (myoclonus)
- Slurred speech (dysarthria)
- Involuntary movements
- Shrinking of the brain (cerebral atrophy)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
