Occipital lobe stroke and memory loss

Recent reports from neuroimaging show the occipital lobe may be involved in the processing of implicit memory (IM), especially the perception type of IM processing. A stroke is often caused by problems with blood flow in the brain, such as a blocked artery or an artery that has burst. Damage to the occipital lobes causes visual problems, which vary based on the stroke ’s severity.

An occipital stroke is a stroke that occurs in your occipital lobe. If you’re having an occipital stroke , your symptoms will be different than symptoms for other types of strokes.

This describes loss of half of the vision out of each eye. A stroke survivor who has homonymous hemianopia is not able to see objects that are on the opposite side of the stroke. A stroke of the occipital lobe can cause vision loss or partial vision loss of one eye or both eyes. Because of the way the blood vessels are arranged in the brain, occipital lobe strokes are less common than strokes affecting the frontal lobes , temporal lobes , and parietal lobes.

Damage to the cerebellum does not cause loss of vision or severe memory loss , but the same major blood vessels that provide blood supply to the cerebellum (the basilar and vertebral arteries) also supply the brain regions responsible for these other functions. Because the thalamus shares its blood supply with the brainstem, occipital lobe and temporal lobe of the brain, strokes in those areas can also affect the thalamus. Depending on which lobe is affecte the survivor may experience visual field loss ( hemianopsia ), memory loss or problems with swallowing and breathing.

Brain Lobes and Effects of Stroke. The location and size of your stroke injury will determine what functions will be lost or changed. The brain can be divided into main areas: the cerebrum, cerebellum and brain stem. Each area in the brain controls different functions or skills.

In today’s article, we’re covering all the functions of the occipital lobe and the symptoms of occipital lobe damage. Damage to them may cause deformation of the visual field and of perception of size, color and shape. Treatment options included visual search training, visual awareness, typoscopes, substitutive prisms, low vision aids, refraction, and occlusive patches. The occipital lobe is the rear portion of the cerebral cortex , located at the lower back of the head.

Learn vocabulary, terms, and more with flashcards, games, and other study tools. Memory loss , visual field cuts and. Most people who have vision loss after a stroke will not fully recover their vision. Some recovery is possible, usually in the first few months after a stroke. Glasses or contact lenses generally will not help vision loss due to stroke.

Ophthalmologists, orthoptists, doctors and occupational therapists can advise on the best management for you. That means that a stroke has potential to create some visual deficits, such as poor visual memory, decrease in balance, decreased depth perception and reading problems, to name a few. They are found within the brain’s largest division, the forebrain.

There is one occipital lobe in both hemispheres of the brain. It’s a type of ischemic stroke and accounts for about one-fifth of all strokes. It borders with the parietal lobe (from which it is not clearly demarcated) and the temporal lobe. Symptomatic occipital seizures can start at any age, as well as any stage after or during the course of the underlying causative disorder.

Occipital lobe epilepsies are etiologically idiopathic, symptomatic, or cryptogenic. A stroke impacting the right occipital lobe may result in loss of vision in the left visual field. The MRI brain (figure 1) was obtained from a young postpartum woman with a left occipital infarction with hemorrhagic conversion, which resulted in loss of vision in her right visual field. A tumor in the occipital lobe may mean loss of vision in one eye or sometimes both eyes. I was completely blind at first.

I recovered most of my vision except thirty percent in each eye. I am blind in the upper left quadrant of each eye.
