Lateral pontine syndrome, also known as Marie-Foix syndrome or Marie-Foix-Alajouanine syndrome [1] is one of the brainstem stroke syndromes of the lateral aspect of the pons. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of ...
Human brainstem blood supply description. Basilar artery is #7, and pons is visible below it. Medial pontine syndrome results from occlusion of paramedian branches of the basilar artery .
Many neuropsychiatric disorders precipitate from alterations to NE modulated neurocircuitry: disorders of affect, anxiety disorders, PTSD, ADHD and Alzheimer's disease. Alterations in the locus coeruleus (LC) accompany dysregulation of NE function and likely play a key role in the pathophysiology of these neuropsychiatric disorders.
In some cases AUD can cause other brain disorders to worsen itself, or the symptoms of the disorder. An example of this can be seen in some with Obessive-Compulsive Disorder (can typically include anxiety “triggers” that often cause an individual to have very specific compulsions or obsessions).
The symptoms include sudden onset of vertigo, vomiting, nystagmus, dysarthria, falling to the side of the lesion (due to damage to vestibular nuclei), and a variety of same-side features including hemiataxia, loss of all types of sensation of the face (due to damage to the principal sensory trigeminal nucleus), facial paralysis (due to damage ...
The main supply of blood to the brainstem is provided by the basilar arteries and the vertebral arteries. [14]: 740 It is important to note that there is a bit of variability in how these arteries connect and supply blood to the brain, such as where the arteries fuse or are reinforced. The variability that exists allows for syndromes to be ...
Central pontine myelinolysis is a neurological condition involving severe damage to the myelin sheath of nerve cells in the pons (an area of the brainstem). It is predominately iatrogenic (treatment-induced), and is characterized by acute paralysis, dysphagia (difficulty swallowing), dysarthria (difficulty speaking), and other neurological symptoms.
The pons is also called the pons Varolii ("bridge of Varolius"), after the Italian anatomist and surgeon Costanzo Varolio (1543–75). [1] This region of the brainstem includes neural pathways and tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus .
