Question

____________ and ____________ can present w/ either no real motor change but with pain, or weakness/numbness but not typically with sudden involvement of bladder and bowel dysfunction.

Answer 1

Upper and lower motor neuron lesions can lead to symptoms like muscle weakness and sensory changes but do not usually present with sudden bladder and bowel dysfunction.

Step-by-step explanation:

Conditions like upper motor neuron (UMN) lesions or lower motor neuron (LMN) damage can present with varying symptoms. UMN lesions can lead to symptoms such as muscle weakness, increased deep tendon reflexes, and spasticity, which involves an excessive contraction in resistance to stretch. In contrast, LMN damage may result in muscle weakness or atrophy, and reduced reflexes. Both UMN and LMN damage can be associated with pain or sensory changes, such as numbness. However, sudden involvement of bladder and bowel dysfunction is not typically a presenting symptom of UMN or LMN lesions and can suggest more acute conditions, such as cauda equina syndrome, which requires immediate medical attention.
