Week 3 - Syncope / Weakness / Dizziness Flashcards

1
Q

Syncope

Syncope definition

Can they seize?

What is the pt like after the syncope?

A

Temporary/transient loss of consciousness associated with loss of postural tone, insufficient blood flow to the brain.

Also called fainting or “passing out” - usually occurs due to hypotension

They can have BRIEF seizure activity

The pt is NOT altered or post-ictal afterwards

Q

Weakness

A

A decrease in physical strength or energy

Many different symptoms and presentations

May represent neuromuscular weakness, fatigue, malaise, or pressyncope

Hx and physical exam is key to help narrow the differential

Stress cardiomyopathy

30
Q

POTS – Postural Tachycardia Syndrome ​

What is it?

Who does this affect?

A

A genetic disorder characterized by orthostatic intolerance—too little blood returning to the heart when moving from a lying down to standing up position.

This syndrome affects 1 in 100 people, and is generally diagnosed between ages 15 and 50. It is most frequently seen in young women, less than 35 years of age. ​

The cause of this disease is poorly understood, but researchers suspect that the syndrome may have more than one cause.​

1in100 people
Age 15-50y old
Women LESS then 35y old

31
Q

Stokes-Adams Syndrome

What is it?

A

32
Q

A

chronic neurological disorder that affects the brain’s ability to control sleep-wake cycles.

Vivid dream-like images or hallucinations

AND

Total paralysis just before falling asleep or just waking up

33
Q

Cataplexy

What is it?

What triggers it?

it is the 1st symptom to appear in narcolepsy, usually it’s misdiagnosed as a seizure disorde

A

A sudden loss of muscle tone while a person is awake leads to weakness and a loss of voluntary muscle control.

The symptoms of cataplexy may appear weeks or even years after the onset of EDS. Some people may only have one or two attacks in a lifetime, while others may experience many attacks a day. In about 10 percent of cases of narcolepsy, cataplexy is the first symptom to appear and can be misdiagnosed as a seizure disorder

sudden-strong emotions like laughter, fear, anger, stress, or excitement
