Stroke in left occipital cortex

Common Questions and Answers about Stroke in left occipital cortex

stroke

Avatar n tn ) lesions specifically in the left frontal, and bilateral occipital lobes (left and right) and the only larger sized lesion is the 7mm parieto-occipital lesion adjacent to cortex and this later MRI did not find a tiny T1 pituitary lesion.
Avatar n tn An noteworthy area of increased signal intensity in the left medial occipital lobe. There is no bleeding into the lesion on the gradient-echo study. The lesion is in the superior bank of the calcarin cortex and to a lesser extent into the parietal region, consistent with her inferior contralateral visual field loss. The area had increased signal intensity on the diffusion weighted image, but I do not see a similar dark area on the ADC map, raising curiosity that this area is somewhat older.
Avatar f tn just one. If present in both eyes, this is suspicious for a process affecting the occipital cortex on the right side, the part of the brain responsible for the left visual field. If the visual defect only was present in one eye, then the problem is more likely involving the optic nerve.
Avatar f tn A large hypodense lesion noted in left cerebellum and left occipital lobe without perifocal oedema. Basal cisterns are normal. Fourth, lateral and third ventricles are normal in size and shape. IMpression : 1) cerebral atrophy, 2) large infract in left PCA territory Is that means she has had a stroke? Please any one know what this mean.
635835 tn?1272539383 I had a new brain MRI done in January. The report said it was normal, but the neurologist just called and said that there is a "spot" in the right occipital cortex. She wants me to come back to the clinic and see a movement disorder specialist because I've been having foot spasms and pulsing into plantar flexion with stretching into dorsiflexion, and see a neuro-ophthalmologist for the many visual symptoms that have been increasing lately.
Avatar n tn I have been experiencing constant blurred vision in my left eye for the last 2 months, with frequent episodes of brief, stabbing pain through the center of my eye. The pain goes away, but the blurred vision never does. My doctors have already ruled out optic neuritis/MS, because I was experiencing shorter episodes of this same issue earlier this year. All of the MRIs/MRA/CT scans/blood tests I had came back normal.
Avatar m tn Your visual symptoms are consistent with ocular migraine. Vision is processed in the occipital cortex, which is located in the back part of the brain. With ocular migraine, the occipital cortex is irritable (for any number of reasons) and is "signalling" vision information which is not really coming from your eyes. You do not have to get a headache for the diagnosis to be ocular migraine.
Avatar f tn Hi I am just trying to find out the best and most recent ways to handle thalamic stroke pain. My father in law has been suffering for the past two years and can't seem to find anything to help the pain and tightness in his right hand and leg. It hurts him to do anything except lay in bed or sit in a chair. I know how bad he hurts because he was a man of projects prior to his stroke and now he does nothing because of the pain.
Avatar m tn Cortical dysplasia is a congenital abnormality where the neurons in an area of the brain failed to migrate in the proper formation in utero. Occasionally neurons will develop that are larger than normal in certain areas. This causes the signals sent through the neurons in these areas to misfire, which sends an incorrect signal. It is commonly found near the cerebral cortex and is associated with seizures and may be associated with some level of developmental delay(s).
Avatar f tn The parietal lobes have a lot to due with the motor cortex and motion. The occipital lobe (back of the brain above the cerebellum) contains the visual cortex. The Optic Nerve runs from the retina to the optic cortex, so lesions anywhere along that path can cause ON. All of these areas are considered "supratentorial." The "infratentorial" brain is the the Brainstem, cerebellum and the deep structure like the thalamus and hypothalamus.
Avatar m tn Dear sir, my brother 26 yrs old has lost his left eye vision in accident 1 month ago, afrer the complete check up the eye specialist told everything is ok with eye, this is case of neuro so we consulted neurologist but not got any progress Still may be he got injuries in his optic nerve, as 1 month has passed and still no improvement, so please guide me what to do, that he can regain his sight and life, pleaee sir
Avatar n tn This suggests the presence of demyelination perhaps on the basis of ischemic change. There is slight increase in signal in the left occipital region on the diffusion weighted sequence suggesting that there may be some recent ischemic injury in the posterior white matter in the distribution of the posterior cerebral arteries. This must be correlated with clinical findings.
Avatar m tn Last week I suffered a cryptogenic stroke of the left temporal cortex that presented with garbled speech and difficulty drinking from a cup. (Both symptoms have since resolved completely.) At hospital admission I was also extremely dehydrated and and my potassium was very low following several days of severe diarrhea. (I have no history of chronic hypokalemia.) Currently the only change from pre-stroke is a decrease in heart rate from a normal range of 60 to 70 to 42 to 55.
660872 tn?1238641245 I have left facial pain 7 out of 10. Left occipital headache, 6 out of 10 pain. Nausea ++. Vertigo, slight to moderate. Left hand tingly and left foot and up to mid calf tingly, numb. Visual disturbance had gone away but has come back with central bright gold coloured circle that is increasing in size again. Hope it doesn't get worse. Still migraine type thing ? Chirley Oops, now have central vision loss. Just started. Weird experience, hard to see what I'm doing.
Avatar f tn I get a sharp shooting pain that starts at the left side of the base of my skull, travels up my head, paralyzing my tongue and left side of face, and causing numbness on my head. Each time I look like I have had a stroke, although some episodes are stronger than others. The paralysis goes away after a couple of minutes. A dull headache and very mild numbness lingers for a few hours after. Neck soreness (left side only) lasts sometimes for days.
Avatar f tn m lost as to why the lesion in the right corona radiata is not suggestive of MS, keep in mind my husband was told in 1994 that he had MS. I also don't see a comparsion to the previous MRI. Any ideas or suggestions? What do you all think about this MRI?
1041487 tn?1256327719 t think you will find a single survivor that was told that this particular area in the brain was damaged. In my case i was told I had a stroke with obvious hemiplegia and hemiparetic affects, but I was never told that 2/3rds of my motor cortex was dead and all of my pre-motor cortex was dead. Without that knowledge no one can compare their stroke therapies to anyone elses.
1310035 tn?1305621642 That means that the vision issue is either refractive (glasses should help) or I guess there could be an issue with visual processing in the occipital lobe (pretty rare.) My vision is a pain. After steroids, I waited about 8 weeks and when I couldn't stand it anymore, I went to a difficult vision ophthalmologist. He corrected things as best he could. I still have ghost images, but can see 20/20 corrected.
Avatar m tn From there a second axonal signal moves along the optic radiations and the posterior periventricular white matter to the occipital cortex. This stimulates the striate cortex to generate a large electrical potential which is detectable on the EEG sensors. The whole trip (the latency) normally takes about 100 milliseconds. This latency is called the P100. White matter lesions anywhere along this pathway will slow or even stop the signal.
Avatar f tn There are multiple causes for seizures, and certainly a alcohol intake or withdrawal can trigger a seizure but usually in a patient who is susceptible to seizures, does not happen in every patient. A patient who has suffered a stroke, specially in the cortex (outer part of the brain), may be susceptible to have seizures coming from the area that suffered the damage from the stroke.
Avatar n tn Hi, Today, for the second time in about 5 weeks, I experienced a sudden loss of peripherial vision in my left eye. I was able to see well with my right eye, but with my left I had blind and blurry spots. The problems were more prominent as I tried to see to my left. I could not se my left hand if I put it toward the left of my face. When trying to read my sight would miss entire words. I had no pain at the moment, but later when my vision returned to normal, I had a terrible heachache.
Avatar m tn Thank you for your comments. I already took this case to court, and my mother's cousin is insisting that she was given the house as a gift by my grand mother. All documents needed to change the tile of house to my mother's cousin does not exist after 15 years. Thus, I have to prove she was mentally incompetent in her decision making. I would like to know what "CB infarction, extended(Diffuse cortical injury)" mean. I think it is related to the brain.
Avatar m tn My brother had a stroke 4 years ago with right side paralysis and now he has recovered but still his speech is not clear and cannot pronounce words. Also he has difficulty understanding and has memory loss. Also he has lots of pain in his left hands and legs.
Avatar n tn That makes sense to me. I also suffer from a herniated C4-C5 disc. Could pressure from the hernia be constricting a vessel?
Avatar f tn If there is any knowledge or advice in this area, help would be greatly appreciated. The stroke occurred in my frontal right cortex and I had a smaller, secondary stroke in the middle of my brain on the right side as well.
Avatar f tn The lesion may well be in the visual pathway. The pathway extends from the retina all the way up to the visual cortex in the occipital lobe. If her blurring of vision is of a recent onset, it is a good idea to investigate further for demyelination. Is there a family history of multiple sclerosis? She is young and it is very rare to see a 9 years old diagnosed with MS. Her age is on her side. Please let me know what happens at the pediatric neurologist's office.
Avatar m tn Am not sure if am in right Forum ! But am posting my question anyway. On 3rd of December 2009, our son was suffering from fever and severe pneumonia. During the course of transportation to hospital, it seems ambulance attendants did not masked oxygen mask properly to our son, as a result they caused lack of supply of oxygen and hence damage to brain cells.
