MND Flashcards
What is MND?
Progressive paralysis due to loss of motor neurones.
MND has sensory involvement
False
MND is idiopathic
True. Note: glutamate excitotoxicity plays an important role and there is associated chromosome 4 abnormality.
What precipitates MND?
Viral infections, toxins and trauma.
Sclerosis is greater at the higher levels than the lower levels
False. Greater at the lower levels
Destruction of which cells leads to LMN disease?
Anterior Horn cells.
Sclerosis of the lateral and anterior columns occur.
False, only the lateral coloumns
Anterio horn & Motor Nuclei of brain stem cell destruction leads to LMN signs ?
True
Corticobulbar tract destruction leads to UMN lesion signs.
True, increased gag reflex, small tight tonge sticking out.
Pseudobulbar palsy is caused by destruction of motor neuron nuclei of brainstem.
False, Bulbar palsy
Pseudobulbar palsy is caused Corticobulbar tract destruction.
True
Progressive muscle Atrophy (LMN) has a better prognosis than ALS
True (ALS = UMN & LMN)
Common Problems (signs) of MND include; Muscle atrophy & muscle weakness.
True
Common Problems (signs) of MND include Respiratory and bulbar function problems.
True
Common Problems (signs) of MND include Decreased muscle tone.
True, though increases may also be present depending on site of damage.
