CM- Neuro -10- Movement Disorders
| Question | Answer |
|---|---|
| What are tremors | rhythmic oscillation of the body usually in distal body parts |
| What are the major metabolic causes of tremors | uremia and liver failure |
| what are the major endocrine causes of tremors | hypoglycemia, pheochromocytoma, thyrotoxicosis |
| What are the common drugs that are associated with tremors | Caffeine, Theophylline, Amphetamines, Alcohol, Lithium, Beta-Agonists, Bronchodilators, tricyclics, Valproic Acid, Amiodarone, Nifedipine |
| What is an action tremor/intention tremor | tremor provoked by movement usually indicates brain stem disorder or cerebellar disease |
| What is a resting tremor and what is it common in | tremor that is present in absence of voluntary muscle activity usually seen in Parkinson's |
| What is a postural tremor | tremor that occurs while trying to maintain posture, physiologic tremor and drug induced |
| What disease is associated with chorea (choreoathetosis movements) jerking | Huntington's Disease |
| What type of tremor or movement disorder is characterized by involuntary jerky nonrhythmic semi purposeful movements that occur predominantly in the limbs but can be in head, neck, lips, tongue | tardive dyskinesia |
| What type of movement is seen in senile chorea | buccolingual dyskinesia |
| What type of movement disorder can the following drugs induce- Phenytoin, L-Dopa, Psychotropic's | Drug induced Chorea |
| What type of movement disorder is marked by large flinging ballistic movements of the arms and legs | Hemiballismus- associated with Lacunar CVA, subthalamic basal ganglia disorders |
| What are the following characterized as? Spasmodic torticollis, segmental and generalized dystonia | focal dystonias |
| What type of movement disorder are the following characterized as? Oculogyric crisis, torticollis, tongue protrusion and opisthotonos | Acute Dystonic Reaction |
| What is the tx for acute dystonic reaction and paroxysmal dystonia | botulinum toxin |
| Which is more common Parkinson's' tremor or essential tremor | Essential tremor affects any age usually >60, affect both sexes, no racial predilection |
| What are something's that can reduce the essential tremors a pt experiences | alcohol and beta-blockers |
| Your pt has what you think is an essential tremor just to be careful what intoxication should you rule out | manganese or organic solvents can case essential like tremors |
| What type of inheritance is seen with essential tremor | autosomal dominant |
| what conditions can worsen essential tremors | emotion, hunger, and fatigue |
| How do essential tremors typically start | in one upper limb then involves other legs are less likely to be affected |
| what activities of daily living are affected most by essential tremors | hand writing, holding up a glass small manual dexterity tasks |
| What is the biggest difference between essential tremor and Parkinson's disease | essential tremor is tremor with action while Parkinson's exhibits a tremor at rest |
| One of your differentials of essential tremor is hyperthyroidism how would you rule this out | look for other s/sx of hyperthyroidism they will have increased appetite, weight loss, increased sweating, exophthalmos and lid lag, tachycardia, abnormal thyroid function tests |
| One of the differentials of essential tremors is cerebellar disease how would you rule this out | look for other s/sx of cerebellar disease such as tremor increases with intensity as target is approached, slow rate of tremor, broad ataxic gait, movements are clumsy, get brain imaging, hypotonia, past pointing |
| What questions would you want to ask a pt with suspected essential tremor | what makes it go away- alcohol, sleep. What makes it worse- Anxiety; Family hx |
| What tests should you order in suspected essential tremor pt | get thyroid tests, CT/MRI scans to rule hyperthyroidism and Cerebellar disease or tumor |
| What is the tx for essential tremor | most just need reassurance that they don't have Parkinson's but if activities of daily living are impacted beta blockers are effective |
| What is often the first line therapy for essential tremors especially in younger pts | Beta Blocker such as propanolol, Primidone is now being used as first line as well |
| What are some second line therapies for essential tremors | Anticonvulsants such as gabapentin and topiramate |
| When would surgery be considered as tx option for essential tremors | when all other tx has failed and the tremors are debilitating (surgery involves deep brain stimulation or thalamotomy) |
| what are the guidelines for starting propanolol to tx essential tremors | start low and go slow |
| What are the contraindications for using propranolol to tx essential tremors | hypersensitivity to tx, sinus bradycardia, heart block > 1st degree, sick sinus syndrome, overt heart failure, asthma |
| What type of drug is primidone that is used sometimes to tx essential tremors | antiepileptic drug start low and go slow with elderly |
| T/F clonazepam is ineffective at tx essential tremors | F it is effective but should be reserved for after Beta-Blocker or primidone |
| What is a common cause of restless leg syndrome | Iron deficiency |
| What are tx for restless leg syndrome | Iron supplements if serum iron is low, Sinemet, dopamine agonists (pergolide, ropinirole) and Gabapentin can all be used |
