Final answer:
Lesions in the right cerebellar hemisphere can lead to motor control issues such as ataxia, dysmetria, intention tremor, and dysdiadochokinesia on the same side of the body.
Step-by-step explanation:
The symptoms of a lesion in the right cerebellar hemisphere can include issues with motor control on the same side of the body (ipsilateral). These symptoms manifest because of the cerebellum's role in coordinating movement.
The presentation may include ataxia, which is the lack of voluntary coordination of muscle movements, dysmetria, the inability to judge distances or scale, and intention tremor, which is a shaking that occurs during deliberate movements.
Additionally, the individual might have difficulty with tasks that require rapid alternating movements, known as dysdiadochokinesia. While these symptoms can severely impact a person's ability to perform daily tasks, it is important to note that they only affect motor control and do not impact intelligence or memory.
