1
Q

What is the chief characteristic of seizures?

A

They are stereotyped, recurrent events (i.e. each episode is the same)

2
Q

Is there usually a trigger or prodrome associated with a seizure?

A

No (this is more a sign of syncope)

3
Q

If, after a collapse, a patient is not aware of what happened - does this suggest a seizure or syncope?

A

Seizure (in syncope, the patient will generally know what has happened)

4
Q

If, after a collapse, there is rapid recovery - does this suggest a seizure or syncope?

A

Syncope (in a seizure, the patient will be drowsy for a long time after)

5
Q

When dealing with a possible seizure history, it is really important to get information from who? What can you ask them to do?

A

A witness (i.e. take a collateral history), ask them to take a video if it happens again

6
Q

What are some important questions to ask about the onset of a collapse?

A

What was the person doing at the time? Were there any triggers? What was the environment like? What did they look like before? Were there any preceding symptoms?

7
Q

What is a syncopal seizure?

A

When a person faints but doesn’t lie flat which results in small jerks

8
Q

If there is a description of someone collapsing, being stiff and rigid followed by jerky movements, what does this suggest?

A

Generalised tonic clonic seizure

9
Q

What are two things which may occur during a collapse which (despite belief) are not specific for epilepsy?

A

Tongue biting and urinary incontinence

10
Q

What should you ask about the duration of a collapse?

A

How long the whole episode was, and how long any particular components lasted for i.e. tonic phase/clonic phase

11
Q

What are some important things to ask about regarding the aftermath of the collapse?

A

Speed of recovery? Drowsiness/disorientation? Any residual deficits?

12
Q

What are some risk factors for epilepsy that you may want to ask about when taking a history from a person with collapse?

A

Premature or very late birth/any time in special care, seizures in the past, head injury, family history, drugs/alcohol

13
Q

What are some important things to ask about in the social history of a person possibly presenting with epilepsy?

A

Driving and occupation

14
Q

When taking a collateral history for a possible seizure, what should you ask the person to do?

A

Describe the episode in simple terms, and ask for a demonstration of movements if possible

15
Q

What is important to remember about nocturnal seizures?

A

The same thing will happen every time (this is a good question to ask a bed partner)

16
Q

What are some drugs which may precipitate an epileptic seizure?

A

Aminophylline/thiophylline, analgesics e.g. tramadol, antibiotics, anti-emetics, opioids (and loads more)

17
Q

Obviously it is impossible to remember every drug that can cause a seizure, but what is one important thing you should check for?

A

Has there been any recent changes to drugs taken (medically and recreationally)

18
Q

If a patient comes to an epilepsy clinic for the first time, are they usually examined?

A

No (the history is much more important)

19
Q

If a patient presents to A+E with collapse, what examination should be done?

A

Neurological

20
Q

If a collapse turns out to be syncope, what examinations should be done? Who should they be referred to?

A

Cardiovascular, including a lying to standing BP measurement. Refer to cardiology

21
Q

If anyone presents with a seizure, what is the most important investigation to perform?

A

ECG

22
Q

Why is it so important to perform and ECG in patients presenting with a seizure?

A

Because seizures can be caused by arrhythmias which can be fatal (e.g. long QT)

23
Q

Should brain imaging always be performed on someone presenting with a seizure?

A

No

24
Q

When is most imaging for a seizure done?

A

After the patient has been seen in clinic

25
Q

When should an acute CT scan be done for someone presenting with a seizure?

A

In any case where there is a chance that the person may require neurosurgical intervention in the next few days

26
Q

Give some specific examples of reasons why a person presenting with a seizure may require an acute CT scan?

A

Clinical skull fracture, deteriorating GCS or failure to be GCS 15/15 4 hours after presentation, focal signs, head injury with seizure, suggestion of other pathology

27
Q

What investigation should never be done to establish the cause of a seizure?

A

EEG

28
Q

When are the only times that an EEG should be done?

A

To classify epilepsy, confirmation of non-epileptic attacks, surgical evaluation for severe epilepsy and confirmation of non-convulsive status

29
Q

What are some conditions which are commonly confused differentials of epilepsy?

A

Syncope, non-epileptic attack, panic attacks/hyperventilation, sleep phenomena

30
Q

How should you manage patients who have had a one off seizure?

A

Counsel the patient and explain what has happened, explain that one seizure doesn’t necessarily mean epilepsy. Explain the risk of recurrence of future seizures and driving rules.

31
Q

What are the DVLA rules for a one-off seizure in someone who drives a car?

A

You can reapply for your license after 6 seizure free months if medical advisors decide there isn’t high risk of you having another seizure

32
Q

What are the DVLA rules for a one-off seizure in someone who drives an HGV?

A

You can reapply for your license if you haven’t had a seizure in 5 years and you haven’t taken any anti-epilepsy medication in 5 years

33
Q

What are the DVLA rules for epilepsy in someone who drives a car, who gets seizures while awake and loses consciousness?

A

You can reapply for your license if you have been seizure free for 1 year

34
Q

What are the DVLA rules for epilepsy in someone who drives a car, who gets all their seizures at night?

A

You may still qualify for a license if it has been more than 12 months since your last attack

35
Q

What are the DVLA rules for epilepsy in someone who drives an HGV?

A

You can reapply for your license if you haven’t had an epileptic attack in 10 years and haven’t taken any anti-epileptic medication for 10 years
