Central Nervous System Flashcards
(70 cards)
What are the main aims of dementia treatment?
Manage symptoms, as there is no cure. CBT can be used for mild to moderate dementia to help with cognitive symptoms.
What types of drugs are associated with increased anticholinergic burden in patients with cognitive impairment?
Drugs with antimuscarinic effects, such as amitriptyline, paroxetine, chlorphenamine, promethazine, olanzapine, quetiapine, solifenacin, and tolterodine.
What is the first line treatment for mild to moderate Alzheimer’s disease (AD)?
Monotherapy with donepezil, galantamine, or rivastigmine (all ACEIs). If ACEI is not tolerated/CI then use memantine for moderate AD.
When can memantine be added to Alzheimer’s Disease treatment?
If a patient is already receiving an Acetylcholinesterase inhibitor (donepizil or rivastigmine) and develops moderate to severe AD, memantine can be added.
Which ACEIs are used (unlicensed) to treat mild to moderate dementia with Lewy bodies?
Donepezil or rivastigmine.
What is the recommendation regarding antipsychotics (APs) for dementia patients?
APs should only be offered if patients are at risk of harming themselves or others, or distressed by hallucinations. Use at the lowest effective dose and review every six weeks due to MHRA warnings about increased stroke and death risk.
What non-drug treatment should be considered for depression and anxiety in patients with mild to moderate dementia?
Psychological treatments such as CBT.
When initiating AED treatment, what dosing strategy is recommended?
Start with a low dose and increase gradually, adjusting based on plasma drug half-life to encourage adherence.
What should be done if monotherapy with a first-line AED is unsuccessful?
Try monotherapy with an alternative AED.
What is the MHRA advice regarding AEDs and suicidal thoughts?
All AEDs may be associated with a small increased risk of suicidal thoughts and behavior. Patients and carers should seek medical advice if mood changes or suicidal thoughts occur, but do not stop or switch AEDs without advice.
What does Category One for AED switching risk include?
Carbamazepine, Phenobarbital, Phenytoin, Primidone - MAINTAIN ON SPECIFIC BRAND.
What are the main symptoms of antiepileptic hypersensitivity syndrome?
Symptoms start 1-8 weeks after exposure: fever, rash, lymphadenopathy (most common 3 symptoms). Other symptoms: liver dysfunction, haematological, renal, pulmonary abnormalities, vasculitis, multi-organ failure. Withdraw drug immediately and DO NOT re-expose.
Under what condition can AEDs be withdrawn?
If a patient has been seizure-free for 2 years.
What driving restrictions apply after a first unprovoked epileptic seizure?
Patients must not drive for 6 months; can then resume driving if they are fit to.
What is the general advice regarding AED use in pregnancy?
Increased risk of teratogenicity, especially in the first trimester and with multiple AEDs. Valproate is highly teratogenic and should only be used if PPP conditions are met and alternatives are ineffective or not tolerated. Lamotrigine and levetiracetam are safer options. 5mg folic acid is needed.
What advice should be given to females who find out they are pregnant while on AEDs?
They should seek urgent medical help and should not stop their AEDs without discussing this with their doctors.
Regarding breast feeding by women on AEDs, what toxicity symptoms of infants should be advised?
Advise on signs of toxicity in the infant. All infants should be monitored for sedation, feeding difficulties, adequate weight gain, and developmental milestones.
What 1st line drugs may be considered for Focal seizures with or without secondary generalisation?
lamotrigine or levetiracetam.
What is the first-line treatment for tonic-clonic seizures in men and women unable to have children?
Sodium valproate. Alternatives: lamotrigine or levetiracetam [unlicensed].
What should be offered as 1st line treatment for myoclonic seizures in males/females who can’t have kids?
Offer sodium valproate.
What additional treatment should be considered if monotherapy is unsuccessful for Dravet syndrome?
Clobazam, stiripentol, and sodium valproate and alternative to this- clobazam and cannabidiol.
How treat Convulsive epilepticus, seizure lasting for 5 or more mins?
Use BZDs, such as diazepam rectal solution OR midazolam oromucosal solution.
What is the treatment for brief febrile convulsions?
Need no specific treatment.
In BPD, what is the recommendation regarding antidepressants?
DO NOT give in patients with rapid cycling bipolar disorder, recent history of mania, hypomania or with mood fluctuations. Stop antidepressant if the patient develops mania or hypomania.
