MS is a __ & progressive disease with patches of damage that can occur throughout the brain & spinal cord.
Autoreactive __ __ & _ __ cross the blood–brain barrier and recognize myelin and __ autoantigens, triggering inflammation & loss of ___ (myelin-producing cells).
Activation of __ cells (brain macrophages) contributes to inflammation and injury with plaque formation and axonal degeneration.
Loss of myelin disrupts nerve conduction with subsequent death of neurons & brain ___.

(Neuromotor disease)
Which term refers to a rare demyelinating disorder caused by a humoral & cell-mediated immunological reaction directed at the peripheral nerves, where it usually occurs after a respiratory tract or gastro-intestinal infection?
Guillain-Barré syndrome
(Guillain-Barré syndrome) –> Progression & manifestations
__ __ – ends in 1-3 weeks – no further deterioration
__ __ – last for several days to 2 weeks
__ __ – remyelination and axonal process regrowth – can last from 4 months to 2 years.
Manifestations include:
(Starts in __ and __ __) Starts with tingling & numbness progresses to
__ of the legs to complete __. Causing __ __
- Acute phase
- Plateau phase
- Recovery phase
- legs and moves upward; paresis; quadriplegia; respiratory insufficiency
(Motorneuron disease)
Which term refers to a worldwide neurodegenerative disorder that diffusely involves lower and upper motor neurons, resulting in progressive muscle weakness, leading to loss of ability to eat, speak, move, and breathe; Where 10% of people have the familial form of the genetic mutation & its a progressively debilitating disease –rapidly fatal – survival time is < 3 years?
Which term refers to the scarring of the corticospinal tract in the lateral column of the spinal cord, refering to the upper motor neuron component of the syndrome?
Amyotrophic lateral sclerosis (ALS)
- Lateral sclerosis
(ALS) –> Manifestations
Manifestations depend on the affected __ __, since specific __ will activate specific muscle fibres
Manifestations include:
__ __ (primary sign); trouble __ cup or __ a pen may occur or they may have trouble __ or __;
choking, __ __, depression, __ __; progress to problems breathing; & can develop ___ at the same time
(Progresses quickly)
- Motor neurons; neurons
- Muscle weakness; lifting; holding; speaking; swallowing; excessive drooling; inappropriate laughter; dementia
(Complex motor disorder)
Which term refers to a complex motor disorder accompanied by systemic nonmotor and neurological symptoms, due to a dopamine deficiency in the basal ganglia?
Etiological classification of __ includes __ __ & __ __
Which term begins after age 40, with incidence increase after age 60, & is more prevalent in males, & is the. leading cause of neurological disability in individuals older than 60?
Which term is caused by some other factor such as trauma, infection, intoxication?
Parkinson’s disease (PD)

- Secondary parkinsonism
(Parkinson’s disease) –> Manifestations Include: (“TRAP” Acronym)
__ __ (starts unilateral & then bilateral), __, __/ bradykinesia (absence or slowing), __ __ (stooped posture – flexed forward, difficulty walking – cannot correct themselves if falling – small stutter step to maintain balance when walking), ___(muscle control loss of ability to speak and swallow)
Start alone or in combination but all present as disease progresses
Also, __ __ (– older than 70 – may be in response to medications taken to control other symptoms)
