Idiopathic Epilepsy
Idiopathic epilepsy
Auch bekannt als: Inherited epilepsy
Kurz gesagt
Idiopathic epilepsy is a common genetic seizure disorder in dogs and an uncommon one in cats. It is characterized by repeated seizure episodes with no identifiable underlying brain disease or metabolic cause, requiring careful diagnostic rule-outs and lifelong medical management.
TL;DR. Genetische Anfallserkrankung: wiederkehrende Anfälle bei unauffälligem Tier dazwischen; Ausschlussdiagnose und lebenslange Therapie.
Zwischen Anfällen wirken die Tiere gesund.
Was ist das?
Idiopathic (inherited) epilepsy is recurrent unprovoked seizures with a normal brain between episodes. Neurons fire in a disorganized surge; no structural brain disease or metabolic toxin is found. Common in dogs; uncommon in cats. Diagnosis is by exclusion.
Ursachen und Risikofaktoren
Presumed genetic. Distinct from reactive seizures (toxin/metabolic) and structural epilepsy (tumor, inflammation, prior trauma). Onset typically young to middle-aged animals. Normal interictal exam and advanced workup support the diagnosis.
Anzeichen
- Generalized tonic-clonic seizures (common)
- Focal seizures, cluster seizures (occasional)
- Status epilepticus: continuous seizure >5 min or no recovery between seizures (emergency)
- Mild anxious rigidity in some breeds (e.g. Labrador, Miniature Poodle)
Manche Rassen zeigen milde Anfälle mit kauernder Haltung und Steifheit.
Diagnose
Physical/neurologic exam between events. Bloodwork and glucose to exclude reactive causes; FeLV/FIV in cats. MRI and CSF when indicated to exclude structural disease. Diagnosis when extensive evaluation is normal.
Blutwerte schließen metabolische Ursachen aus.
Behandlung
Lifelong anticonvulsants to reduce frequency and severity: barbiturates, potassium bromide (generally avoid in cats), zonisamide, levetiracetam; second-line e.g. felbamate. Monitor levels and side effects.
Prognose
Many pets have good quality of life on therapy. Harder with early onset, large-breed cluster seizures. Feline data more limited.
Vorbeugung
No lifestyle prevention. Do not breed affected animals or close relatives in predisposed lines.
Wann den Tierarzt rufen
Emergency: seizure >5 min, clusters within 24 h, failure to regain consciousness, severe post-ictal aggression or continuous head pressing.
