CONVULSIVE CONDITIONS; EPILEPSY
Pathophysiology
In tumour associated epilepsy, non-tumoral surrounding tissue may cause seizures.
Abnormal growth kinetics of tumours can affect surrounding neurons morphologically.
The hippocampus may become involved either directly through tumour extension may contribute to seizure complication.
Tumours can disrupt normal electrical functional patterns, causing increased local coherence.
Cortical connections contributes to generation and maintenance of seizures.
Tumour growth may disrupt the spread of epileptic activity.
The formation of the epileptogenic zone.
Seizures activity may involve the entire brain.
Nursing care
Patients with epilepsy demands long terms commitment from both the general practitioner and specialists.
The prime requirements are a complete diagnosis, selection of treatment and counselling appropriate to individual needs.
The nurse should give the patients who have a high risk of recurrence option and may elect to start treatment.
Most patients with seizures do not need treatment but there are individual exceptions.
All women with epilepsy who become pregnant should asked to contact the specialists.
Patients with non-epileptic attacks should be handled sensitively.
