Freaking amazing video, funny, informative and useful for practice - I tested myself by muting the sound and trying to describe the movements, then rewinding and listening to your description. Thank you so much! For fellow students watching, here are the notes I took on the video (if I've written anything wrong I will edit my comment):

Movement disorders
• Involuntary or voluntary movements
• Unilateral or bilateral - worse on left or right?
• Rhythmic
○ Frequency - high or low
○ Amplitude - high or low or moderate
○ Scenario
§ Rest
§ Movement
§ Task
○ Abolition - disappearance on task or adopting a posture
○ Axis - changing axis from x to y or vice versa suggests psychogenic
○ Definitions
§ Dystonic tremor "no-no of the head"
□ Pt can sometimes stop it such as by touching their chin
□ Some pts find a null point where agonist and antagonist muscles cancel each other out
§ Athetosis - fingers writhing
§ Tremor
□ Rest - can distract themselves, if involving fingers then pill rolling (parkinson's)
□ Kinetic
Postural - tremor in a certain posture, essential (strong family hx - ↓ with alcohol/beta blockers)
Simple
Intention - tremor when trying to move muscles, most often when reaching for something far away, cerebellar ataxia
Task - writer's cramp
• Non-rhythmic
○ Rest or non-rest
○ Bilateral or unilateral
○ Location
§ One muscle, one limb or all limbs
○ Amplitude - high or low or moderate
○ Velocity - fast or slow
○ Stereotypic/Definition
§ Myoclonus - sudden shocking movement, can be large amplitude
□ Asterixis - negative myoclonus where hands drop suddenly (due to hepatic encephalopathy or uraemia) ("liver flap")
§ Chorea - abrupt onset continuous flow mvmts, amphetamines and dopaminergics including cocaine, huntington's, basal ganglia lesions
§ Ballismus - larger amplitude chorea, usually faster than chorea as well
□ Hemiballismus - only one side of the body affected
§ Tics - suppressible but usually at the cost of inner desire to move
§ Dyskinesia - involuntary, erratic, writhing movements of the face, arms, legs or trunk. They are often fluid and dance-like, but they may also cause rapid jerking or slow and extended muscle spasms.
□ Acute dystonia - after taking antipsychotics. High potency (Haloperidol), low potency less likely to cause (chlorpromazine)
Laryngospasm
Oculogyric crisis
□ Levodopa induced/Parkinson's- after taking levodopa or neuroleptics (acute)
□ Tardive (chronic)
Order from acute to chronic: acute dystonia -> akathisia -> Parkinsonian -> tardive

• On examination
○ Tremor
§ Rhythmic
□ Rest - close eyes and count month of years backwards or have them do an activity
Archimede's spiral
Don't rest hand on paper and just let pen touch paper
If smooth then rest tremor, if shaky then kinetic
□ Kinetic
Postural - multiple different positions
Simple - hands hanging down by knees
Intention tremor - finger nose testing
Task - cue from hx, if they tell you they get tremor drinking water or soup, give them a cup and ask them to pretend to take a drink
§ Non-rhythmic
□ Suppressible - tics

Great informative video. The Price is Right in the background was a bonus

[pastmedicalhistory]

i wish i had seen this video before my final medical school exam, !! amazing work

[Sherri-gr]

Thank you!! And By the Gracie of GOD... May you continue to help me better understand what I'm dealing with and going through 🥰

[yasmins.]

I really have to agree with many positive comments. Extremely informative and well put together. Thank you.

[andreavanlierde]

I wish I had a teacher like him when I was studying Medicine!!

[Anonimous]

This is the best video about abnormal movement I've ever seem. Easy to understand and very funny. Thank you so much!

[ldobranici]

I am a psychiatrist (old age) and I found your videos exceptional . Please continue with them. Thank you!

[rwuthenow]

Really enjoyed your video. I'm a rehab nurse and work with TBI patients, studying for my certification exam. I appreciate the help and thanks for the book recommendation!

[docjohnpaul]

Brilliant use of "The Price is Right" sound track. The neurobabble is very well laid out, don't get me wrong, but yes. Perfect soundtrack selection.

[kaushalzaveri]

Hey man! Spread the crystal clear knowledge you have!

[JJMedlife]

I usually don't comment on YT videos I watch for studying but here I really need to leave a comment: THANK YOU for this great work!!!! I really had some difficulties in that topic in neurology and now its much clearer. Thanks! Keep up the hard work, looking forward to see more of you :)

[carlinesimeon]

Absolute great video, content, visual support, theory and its application. Simple, concise to the point and extremely easy to understand and retain. Bravo!

[MacTavish]

great video and awesome opening scene again, please continue producing your content, I'm a final year med student and plan on specializing in Neurology. your videos are very helpful and still entertaining. Learning and laughing in between is the best way to go :)
And to repeat what I commented on the other video, your style of teaching and video editing/production is great!

[Lalaland_lady]

Really great vid. Well presented and important info. And thanks for the plug for Aurora. I love sci-fi too.

[erhansonmez]

[irisng]

Good explanation for my exam but I don’t understand why the background music ? so distracting and makes me what to have tics.

[dmgh]
