This lack of blood, and the the blood carries, causes tissue death and organ failure. The ventilator gives you oxygen through the tube. Recognizing the cranial nerve symptoms can help determine where the stroke occurred. She and my doctors thought it had been a muscle spasm or something, not true movement. The neurosurgeon and neurologist on staff at that hospital immediately performed a surgery and inserted a to relieve the pressure from the accumulation of fluid, in my brain. Both baby and mother did great at home. A stroke affecting both sides of the pons can produce one of the most devastating consequences of brain stem strokes, a condition called locked-in syndrome. Thanks My 84 yr mother had a brain stem stoke and was in hospital for 22 days. Sitting just above the spinal cord, the brain stem controls your breathing, heartbeat, and blood pressure. Each lobe is responsible for different functions. Brain Stem Stroke Symptoms Because the brain stem is responsible for so many functions of the nervous system, symptoms of brain stem stroke are broad and can vary between patients.

The brain brain stem infarction controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy. Brain stem Midbrain Pons Medulla Oblongata Midbrain The midbrain, also called the mesencephalon, is a small region of the brain that serves as brain stem infarction relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate. Pons A major structure in the upper part of the brain stem is called the pons. The pons has two over-arching roles. The first is the regulation of breathing. In the pons, there is a structure called the pneumotaxic center. It controls the amount of air breathed and breaths per minute, which is known as the breathing rate. In addition, the pons is involved in the transmission of signals to and from other structures in the brain, such as the cerebrum or the cerebellum. The pons is also involved in sensations such as hearing, taste, and balance. Finally, the pons is also involved in the regulation of deep sleep. Medulla Oblongata The medulla oblongata is located in the lower portion of the brainstem. It is very important in things like heart rate and blood pressure. It's responsible for many reflexes in the body, or involuntarily controls, such as vomiting, sneezing, and coughing. Involuntary Functions Breathing Heart Rate Swallowing Reflexes to seeing and hearing Startle Response Autonomic Nervous System Sweating B lood Pressure D igestion T emperature Affects level of alertness Ability to sleep Vestibular Function Sense of balance Observed Problems Decreased vital capacity in breathing, important for speech. B alance M ovement Dizziness Vertigo N ausea Sleeping difficulties Insomnia The brain stem contains the fibers which connect the brain to the spinal cord and cerebellum. Strokes within the brain stem may be localized by the pattern of deficits caused by the interruption of these nerves. Brain stem strokes are often caused by mechanical obstruction of blood vessels, which might happen during a high speed chiropractic manipulation of the neck, or some other event that causes a very forceful neck movement, such as after a roller coaster ride. Vertigo spinning is a common early symptom of brain stem strokes. A large stroke in the upper brain stem may sever the connections between the brain and the body. In such an instance, a person may retain consciousness and intelligent thought but become entirely paralyzed except for eye movements. This is called the locked-in syndrome. Locked-in Syndrome A condition resulting from interruption of motor pathways in brain stem infarctionusually by. This disconnection of the motor cells in the lower brain stem and spinal cord from controlling signals issued by the brain leaves the patient completely paralyzed and mute, but able to receive and understand sensory stimuli to the. Communication Communication may be possible by eye gazing to letters or words on aby code using blinking once for yes and twice for noor movements of the eyes staring at objects, people, etc. A stroke affecting the brain stem is potentially life threatening since this area of the brain controls functions such as breathing and instructing the heart to beat. Brain stem stroke may also cause double vision, nausea and loss of coordination. Thalamus The is a small structure within the brain located just above the brain stem between the cerebral cortex and brain stem infarction midbrain and has extensive nerve connections to both. It works to correlate several important processes, including consciousness, sleep, and sensory interpretation. Cranial Nerves The are composed of twelve pairs of nerves that emanate from the nervous tissue of the brain. The function of the cranial nerves is for the most part similar to the spinal nerves, the nerves that are associated with the spinal cord. Apart from sensory functions there are also some that work as motor nerves or mixed nerves. Stroke Warning Signs Sudden numbness or weakness of the face, arm or leg, especially on one side of the body Sudden confusion, trouble speaking or understanding Sudden trouble seeing in one or both eyes Sudden trouble walking, dizziness, loss of balance or coordination Sudden, severe headache with no known cause Rated as a top 5 stroke information web site by: We comply with the information:.
