Patients affected with epilepsy suffer from mild to severe seizures any time and at any place rendering life of person dependent over others, some time seizures may turn in to life threatening one. In some condition in epilepsy seizures last for more than 5 minutes and recurrence is higher almost throughout the day. Such patients are required to hospitalized and are required to be given anticonvulsant drugs which belong to Barbiturates, Benzodiazepines, valporic acid, and fosphenytoin , phenitoin and so on.
Many times drugs used to treat epilepsy are ineffective because of adaptation or drug resistance, and patient continues to suffer. Epilepsy is caused by excessive abnormal stimulative activity of brain cells. The underlying causes of which may be many like damage to brain cells in neonatal stage of life or immunological or infection to brain cells.
The medical device RNS Stimulator is approved by US FDA which when implanted can control seizures before they originate and are observed in as clinical conditions. Medical device RNS Stimulator can detect excessive abnormal activity of brain cells and trigger its deactivating electric impulse which calms down the excessive abnormal brain cell activity.
RNS Stimulator consist of two electrodes which are implanted over the surface of brain where excessive brain cell activity is detected.
In a clinical evaluation it is observed that this device successfully reduced the occurrence of seizures to almost 50%.
Precaution : Patient with RNS Stimulator implanted must avoid following procedures as they may damage brain cells by causing heat or electric impulse
1)Magnetic resonance imaging (MRI)
2) Diathermy procedures,
3) Electroconvulsive therapy (ECT)
4) Transcranial magnetic stimulation (TMS).
