Final answer:
Cerebellar ataxia is the condition caused by stroke, tumor, and multiple sclerosis, marked by symptoms affecting coordinated movement in ipsilateral limbs, including tremor, dysmetria, and dysdiadochokinesia.
Step-by-step explanation:
The condition that can be caused by stroke, tumor, and multiple sclerosis, and primarily affects the ipsilateral limbs causing tremor, dysmetria, and dysdiadochokinesia, is Cerebellar ataxia. These symptoms are indicative of an issue with the cerebellum, which is involved in the coordination of voluntary movements.
Ataxia itself is a movement disorder that can result from various neurological insults, including those mentioned in the question. Unlike Parkinson's disease, which is characterized by tremor, rigidity, slowness of movement, and postural instability due to the loss of dopamine neurons in the substantia nigra, cerebellar ataxia involves a loss of coordination and balance problems often linked to direct cerebellar damage.
