The focal effect of a lesion to the specific area of damage in the brains. Introduction: A focal effect is the local or specific complications occurred in a particular affected area and it affects the specific functions of that affected area. Cerebrum is the major portion of the forebrain. It is divided into left hemisphere and right hemisphere. It is responsible for the posture and for coordinating voluntary movements. A tumor is a growth of abnormal cells which cause localized dysfunction of the brain related to their locations.

Expert Solution & Answer

Explanation of Solution

Tumor is a space occupying lesion that causes intracranial pressure. The tumor may displace the brain tissue leading to herniation. The cerebral hemisphere controls the muscular functions, speech, thoughts, emotions, reading, writing, and learning. Therefore, the tumor in the cerebral hemisphere will affect the functions controlled by it. However, some systemic signs would also be visible due to complications. Their focal signs and systemic signs are given below:

The systemic sign of dysfunction of cerebellar tumor are given below:

Increased intracranial pressure
Headache
Personality and behavioral changes
Vomiting
Lethargy
Irritability
Seizures

The focal (specific) sign of dysfunction of left cerebellar tumor are given below:

Difficulty in verbal communication
Difficulty in small muscle control
Decreased intelligent quotient
Difficulty in word reading
Difficulty in mathematic calculations
Difficulty in showing positive emotions
Problem with the logical thinking
Difficulty in controlling right side of the body
