The weakness or paralysis is on the side of the body opposite the side of the brain injured by the stroke. This leads to problems with balance or coordination, because the weight of the weak side pulls against the strong side. It can make it difficult for your loved one to sit, stand, or walk, even if his or her muscles are strong enough to perform these activities.
Edit Module Show Tags When Stroke Affects the Thalamus The thalamus is a busy place in the human brain, and a stroke there can have a wide range of effects. By Jon Caswell The thalamus is a busy place in Effects of stroke cva human brain, and a stroke there can have a wide range of effects.
Jeremy Schmahmann, professor of neurology at Harvard Medical School, director of the ataxia unit and member of the cognitive behavioral neurology unit at Massachusetts General Hospital, shared more about this type of stroke. The thalamus, which means "inner chamber" in Greek, is on top of the brainstem near the center of the brain.
It has two halves, each about the size of a walnut. Though relatively small, the thalamus controls a big part of how our bodies function and respond to the world around us.
Only a small part of the thalamus receives input from the outside world or sends information to the outside world. Mostly the thalamus helps the cortex and other cells deep within the brain to communicate with each other. The pain can be intense, usually in the affected arm and hand, and may cause a disturbing burning or freezing sensation.
Some survivors report an intense prickly feeling, like being stuck repeatedly with needles. This can be a roadblock to recovery for a survivor who is doing well in rehab.
Injury to another part of the thalamus may impede movement, balance or strength. Very large strokes in the thalamus can cause many problems. If both sides are injured, destroying connections to the rest of the brain, it may result in coma. Depending on which lobe is affected, the survivor may experience visual field loss hemianopsiamemory loss or problems with swallowing and breathing.
Recovery is more challenging for these strokes because there are many more areas of the brain involved. How a thalamic stroke affects the survivor depends on which part of the thalamus is injured, and whether the injury is on the left or right side of it.
Effects can include loss of sensation, strength and control of movement of the opposite side of the body, memory loss, language deficits aphasiaand a loss of the ability to remember faces. However, according to Dr. Schmahmann, the prognosis for survivors of thalamic stroke is generally better than those who experience stroke in the cerebral cortex.
It is smaller than the thalamus, about the size of an almond.
Like the thalamus it is made of distinct collections of cells called nuclei. The hypothalamus controls body temperature, thirst, hunger and blood pressure as well as sleep and the sleep-wake cycle.
Weight gain or weight loss is also regulated by the hypothalamus. In addition, it controls some metabolic processes and produces hormones that stimulate or inhibit pituitary hormones, which control growth, blood pressure and metabolism, among other things.
It even affects parenting and attachment behaviors. In addition to responding to light, smells and stress, the hypothalamus links the brain to the hormonal system. It acts as a thermostat and either stimulates heat production and retention or stimulates sweating and dilation of blood vessels to cool the body.
The hypothalamus causes fever when microorganisms invade. A stroke in the hypothalamus can cause problems in any of these areas. For instance, a stroke might: Affect hormones that impact fluid control; Cause temperature to fluctuate wildly; and Cause changes in appetite.After stroke, experiencing emotional changes can occur due to natural responses or changes caused by physical effects of the brain.
Learn more about these emotional experiences, changes, and problems after stroke. A stroke survivor who has homonymous hemianopia is not able to see objects that are on the opposite side of the stroke.
A stroke affecting the left occipital lobe of the brain would cause a stroke survivor to have difficulty seeing objects on the right side. Every stroke is different and the effects will depend on which part of your brain was damaged.
Every stroke is different and the effects will depend on which part of your brain was damaged. The good news is that there are things that can be done to reduce the impact of your stroke. Learn more about physical conditions that may impact you, treatment options and tips for managing your post-stroke conditions. The effects of a stroke depend on several factors, including the location of the obstruction and how much brain tissue is affected. However, because one side of the brain controls the opposite side of the body, a stroke affecting one side will result in neurological complications on the . Some effects of stroke include difficulty communicating, memory loss, paralysis, difficulty walking, seizures, urinary tract infections and bladder control issues, depression and increased risk of another stroke. To reduce damage, getting a stroke victim help as soon as possible is key.

Neurologic Side Effects. Aphasia (impaired speech pattern), dysphagia (difficulty in swallowing), reading difficulties, loss of writing ability and hemiparesis (physical weakness on one side of the body) are the most common neurological side effects when stroke occurs in the middle cerebral artery.
The effects of a Stroke typically depend on the extent of the brain damage and where in the brain the Stroke occurred. The brain is divided into four primary parts: left hemisphere, right hemisphere, cerebellum and brain stem, and each area has a responsibility for a particular function or ability.
Some effects of stroke include difficulty communicating, memory loss, paralysis, difficulty walking, seizures, urinary tract infections and bladder control issues, depression and increased risk of another stroke.
