Hemiparesis causes symptoms treatment prognosis complications brain anoxia

Symptoms of hemiparesis

People with hemiparesis have trouble in lifting their arms and feet, not only that but also in shifting their limbs and body parts. Because of this, they have problem with their daily life activities of eating, dressing, grabbing things or objects and even using washroom.

Another symptom of hemiparesis could be of pusher syndrome. The occurrence of this syndrome is characterized by putting more weight on the affected paralytic side compared to the non-paralytic side which is in contrast with other hemiparesis patients. This syndrome mostly happens due to lesions in the posterior thalamus region on both sides or due to multiple lesions in the right hemisphere.


The type, severity and intensity of hemiparesis symptoms depends upon the location of brain where the stroke occurred, injury happened or a tumour had grown.Brain anoxia generally, the left hemisphere injury of human brain results in the weakness of right side and the right side brain injury hamper the left side movement.

• left hemisphere stroke or injury: there are many more symptoms, but a person after left hemisphere stroke faces 2 of these below mentioned problems:

• partial paralysis or sensory disturbances in the right side limbs, hands, legs, feet and even in facial muscles.

• hemianopia (reduced vision of right side of both eyes).

• agnosia (problems with object recognition).

• chronological problems (problems with time, cause, effect).

• reduced analytical skills.

• low memory and verbal skills.

• chances of mood swing rapidly and easily overwhelmed by emotions.Brain anoxia

• right hemisphere stroke or injury: stroke in the right hemisphere can generate the following symptoms:

• weakness or hemiparesis in the left side of the body.

• sensory impairment.

• left neglect or denial of having paralysis and significant reduction of insight into the problem that stroke has caused.

• visual problems like blurred eyesight.

• problems with spatial orientation and direction.

• inability to comprehend maps.

• inability to identify or find objects.

• inability to identify or locate different body parts.

• behavioural issues like depression, inappropriateness, impulsivity, etc.

• problems with memory.

These left and right hemispheres are also divided into lobes (frontal lobe, occipital lobe, temporal lobe and parietal lobe).Brain anoxia so, the hemisphere injury along with the type of lobe affected produces hemiparesis and the other specific symptoms. The degree of injury is high with cerebral strokes; cerebral strokes most often result in hemiplegia (complete paralysis) instead of hemiparesis.

Treatment of hemiparesis

Rehabilitation and home based exercise with physical therapy can improve the mobility of the limbs of affected side slowly. Regular activity and practice with repetition can improve the control on the limbs of an individual with hemiparesis. It can also rebuild the neural connection.

A patient of hemiparesis must be under the hands of qualified and certified physiatrists, physical therapists with knowledge of limb movements to treat disabilities, speech therapists and occupational therapists.Brain anoxia

There are types of treatment which are mentioned below:

• botox/baclofen for hemiparesis: there are a number of studies which demonstrate that if the limbs are tightened up and are difficult to move, then relaxing the muscle helps to make them move easily. Injection of botox and application of baclofen helps to relax the muscles and thus improve the condition.

• cortical stimulation to treat hemiparesis: this therapy is focused on the stimulation of the “cortex” region of the brain. In this case, an electrode is placed on the membrane which is covering the brain of an individual. Electrode is set to send small electrical impulse to brain while the individual is doing rehabilitation exercises.
