Impaired Cognition Flashcards
Why do patients benefit from consultation with speech pathology?
The diseases & conditions (etiologies) that can cause cognitive communication disorders encompasses the entire spectrum of etiologies in medicine
communication etiologies = medicine etiologies
How is etiology different from pathophysiology?
Etiology
- cause, set of causes, or manner of causation of a disease or condition
- disease/injury
Pathophysiology
- describes the functional changes associated with or resulting from disease or injury
- what you’d expect to see considering disease/injury (etiology)
Both are important in understanding course, prognosis, and treatment of disease or injury
The Etiology of a disease is…
the cause, set of causes or manner of causation of a disease or condition
Pathophysiology of a disease is…
the functional changes associated with or resulting from disease or injury
–> what you’d exprect to see considering disease/injury
_________________ & ________________ are important in understanding the course, prognosis, and treatment of disease or injury
Etiology & Pathophysiology
Name Etiologic Categories
DINT 2I TV (Din’t 2 eye TV) Think too much TV = illness
- Degenerative - neurons decline
- Inflammatory -responses to bacteria
- Neoplastic - causes cancer
- Toxic Metabolic - deficiencies/toxicity ( too much junk food is toxic–> deficiencies)
2 I (eyes)
- Iatrogenic - needed surgery now im damaged
- Idiopathic - who knows why?
TV
- Trauma - lots of gunshots, falls, and sports on TV
- Vascular - stroke/neurologic deficits
What type of disease etiology causes decline in neuronal function?
Degenerative Diseases
(i.e. Alzheimers)
What etiology is caused by responses to bacteria, immunologic reactions, viruses?
Inflammatory Diseases
e.g. Covid-19, meningitis
Which etiology is caused by vitamin deficiencies, complications of kidney and liver disease, hypoxia, hyponatremia, drug toxicity?
Toxic- metabolic diseases
What etiology does cancer fall under?
Neoplastic diseases
What etiology is most common cause of neurologic deficits?
Vascular diseases
e.g. cerebrovascular disease (stroke)
Potential precipitating events (e.g. MVA, fall, gunshot wounds, blast injury, and sports-related injuries all are ________
Trauma
Disease caused by medical examinations or treatment are considered _____ in etiology
Iatrogenic
e.g. nerve damage from surgery
Diseases of unknown causes are called ______________ in etiology
Idiopathic
How are diseases/conditions categorized?
CAR-D-D *think cardi-b
- C-onditions of Immunocompromise (please me song)
- A-cute onset diseases that remain stable or improve (started from the bottom now we here)
- R-elapsing remitting diseases (general downward trend) - (Be Careful)
- D-iseases that worsen - (i Like it)
- D-iseases that are episodic -(WAP)
- Stroke
- TBI
- Abscesses
- Encephalitis
are _______ diseases that are ______ or ______
acute onset diseases
stable
improve
what are acute onset diseases?
Diseases that remain stable or improve:
Stroke
TBI
Abscesses
Enchephalitis
What causes CVAs/Strokes?
lack of blood flow to any area of the brain (including brainstem)
a lack of blood flow to any area of the brain and brainstem would cause…
Cerebrovascular accident (CVA, aka stroke)
What deficits most often result due to the loss of blood flow in the left MCA from stroke?
cognitive-linguistic defecits
What happens as a result of blockage in brain from stroke?
- blockage prevents nearby brain tissure from getting nutrients
- Brain tissue is deprived of oxygen & nutrients, it begins to die
3rd leading cause of death & leading cause of disability
Strokes
700,000 strokes annually
Types of stroke are
Hemorrhagic
Ischemic
Hemorrhagic stroke caused by..
ruptured blood vessel that causes bleeding in the brain
2 subtypes of hemorrhagic stroke
- intracerebral (within the brain) hemorrhage
- subarachnoid ( within arachnoid space) hemorrhage
Name two types of weakened blood vessels that cause hemorrhagic stroke
- Cerebral aneurysm: ballooning, weakened artery
- Arteriovenous malformation (AVMs): tangle of blood vessels; congenital but can become a problem
A ballooning, weakend artery is ____
cerebral aneurysm
A tangle of blood vessels that are congenital and can become a problem are —
Arteriovenous Malformations (AVMs)
Cerebral aneurysms & Arteriovenous malformations (AVMs) usually cause
hemorraghic stroke
What type of stroke accounts for nearly 90% of all strokes?
Ischemic (clots)
2 subtypes of Ischemic clots are
- Thrombotic - forms in artery within brain & blocks blood flow
- Embolic- clot forms & travels in bloodstream then lodges & blocks blood flow
_____ _____ form in arteries within the brain and blocks blood flow causing an ______ stroke
Thrombotic clots; Ischemic
_____ _____ form and travel in blood stream, lodging & blocking blood flow causing ______ stroke
Embolic clot; Ischemic
_______ is the brain’s way of reorganizing neural connections to compensate for injury and disease
Neuroplasticity
