+======Cerebral Hemispheres======
 The human brain is divided into two distinct hemispheres: the left and right cerebral hemispheres. These two hemispheres are connected by a thick band of nerve fibers known as the corpus callosum, which allows communication between the two. Although both hemispheres are involved in most cognitive processes, there are several differences between them in terms of structure and function.

 A patient with Left Hemispatial Neglect (also known as hemispatial neglect or left neglect) may experience the following symptoms:
-  - Inattention to the left side of space: The primary symptom of left neglect is a failure to attend to or process information from the left side of space. This may result in a patient ignoring or failing to respond to stimuli on the left side of their visual field.

 A clinician may observe the symptoms of left neglect during a clinical evaluation, which may involve the following tests:

 These tests, along with a thorough clinical evaluation and a review of the patient's medical history, can help a clinician diagnose left neglect and determine the severity of the condition.
+=====Hyper-emotionalism=====
+Hyper-emotionalism is a phenomenon that can occur following damage to the left hemisphere of the brain. The left hemisphere is responsible for language processing and logical, analytical thinking, and damage to this region can result in changes in emotional regulation and expression.
+The exact cause of hyper-emotionalism following left-sided brain damage is not well understood, but it is thought to be related to a disruption in the normal functioning of the brain's emotional processing system. The left hemisphere is known to play a role in regulating and modulating emotional expression, and damage to this region can result in an overproduction or underproduction of emotions.
+Hyper-emotionalism is characterized by an excessive and intense emotional response to stimuli, often in the absence of an appropriate emotional response. Individuals with hyper-emotionalism may experience sudden, intense emotional outbursts, such as crying, laughing, or anger, in response to relatively minor stimuli. They may also have difficulty controlling their emotions and regulating their emotional expressions.
+In addition to hyper-emotionalism, individuals with left-sided brain damage may also experience a range of other emotional and behavioral symptoms, including:
+  * **Emotional lability**: This refers to rapid and sudden changes in mood, such as quickly transitioning from happiness to sadness or anger.
+  * **Impulsivity**: This refers to acting on an impulse without considering the consequences, and may include impulsive behavior, such as excessive spending or reckless driving.
+  * **Aggression**: This refers to behavior that is intended to cause harm or damage, and may include physical or verbal aggression.
+  * **Apathy**: This refers to a lack of emotional response or interest in the environment, and may include a lack of motivation and emotional expression.
+Diagnosis of hyper-emotionalism following left-sided brain damage typically involves a thorough medical evaluation, including a review of the patient's medical history and a physical and neurological examination. Imaging studies, such as a CT scan or MRI, may also be performed to confirm the location and extent of brain damage.
+Treatment for hyper-emotionalism may involve a combination of medications, such as anticonvulsants or mood stabilizers, and behavioral or cognitive therapies, such as cognitive-behavioral therapy or psychotherapy. In some cases, rehabilitation or physical therapy may also be recommended to help improve overall function and quality of life.
