When do you refer to a seizure?
National guidelines. The NICE clinical guideline says: “If seizures are not controlled and/or there is diagnostic uncertainty or treatment failure, children, young people and adults should be referred to tertiary services soon for further assessment.” ‘Soon’ means being seen within four weeks.
What assessments are needed for seizures?
Pinpointing seizure location
- A neurological exam. Your doctor may evaluate your behavior, motor abilities and mental function to determine if you have a problem with your brain and nervous system.
- Blood tests.
- Lumbar puncture.
- An electroencephalogram (EEG).
What is the evaluation of the first seizure?
The first seizure evaluation rests primarily on the clinical history. An accurate description of the spell is necessary to confirm the diagnosis. Identifying prior unrecognized seizures may change the diagnosis to epilepsy. The interview aims to find specific acute or remote symptomatic seizure etiologies.
When is a seizure first treated?
If drug treatment is started after a first seizure in adults, we suggest at least one year of treatment, except for those at low risk for recurrence, when six months without seizures may be sufficient.
Can a doctor tell if you’ve had a seizure?
Electroencephalogram (EEG) – Using electrodes attached to your head, your doctors can measure the electrical activity in your brain. This helps to look for patterns to determine if and when another seizure might occur, and it can also help them rule out other possibilities.
What are warning signs of a seizure?
General symptoms or warning signs of a seizure can include:
- Staring.
- Jerking movements of the arms and legs.
- Stiffening of the body.
- Loss of consciousness.
- Breathing problems or stopping breathing.
- Loss of bowel or bladder control.
- Falling suddenly for no apparent reason, especially when associated with loss of consciousness.
When do you need an EEG after a seizure?
The timing of EEG recording may be important: investigation within 24 hours of a seizure revealed IED in 51%, compared with 34% who had later EEG. Some patients show discharges mainly in sleep, or there may be circadian variation as in idiopathic generalised epilepsies.
Can a neurologist tell if you’ve had a seizure?
If your doctor thinks you’ve had a seizure, she will probably refer you to a neurologist. When you visit your doctor, he’ll ask lots of questions about your health and what happened before, during, and after the seizure. A number of tests may be ordered which can help diagnose epilepsy and see if a cause can be found.
Will seizures show up on MRI?
Does epilepsy show up on MRI scans? No, not necessarily. An MRI scan can help your doctor understand some of the possible underlying structural causes of your seizures. However, for many people there is no structural cause behind their epilepsy and so the brain scan comes back ‘normal’.
What is the NICE guideline for epilepsy?
The guideline covers diagnosing, treating and managing epilepsy and seizures in children, young people and adults in primary and secondary care. It offers best Home NICE Guidance
What is the first-line treatment for GTC seizures?
First-line treatment in children, young people and adults with epilepsy with GTC seizures only. 1.9.14.1 Offer lamotrigine or sodium valproate as first-line treatment to children, young people and adults with epilepsy with GTC seizures only.
What is the first line of treatment for absence seizures?
First-line treatment in children, young people and adults with absence seizures. 1.9.5.1 Offer ethosuximide or sodium valproate as first-line treatment to children, young people and adults with absence seizures. If there is a high risk of GTC seizures, offer sodium valproate first, unless it is unsuitable.
Should a GP refer a child with epilepsy to a GP?
GPs should refer children with suspected epilepsy to their closest general paediatric service. diagnosis of epilepsy is uncertain i.e. concerns that events may be non-epileptic.
