The main cause of SAH is aneurysm rupture. Diagnosis is via CT scan or lumbar puncture. Treatment involves securing the aneurysm with coils or clips to prevent rebleeding, as well as managing complications like vasospasm, hydrocephalus, electrolyte imbalances, and seizures. The goal is to prevent additional bleeding and optimize the patient's recovery.
Tbi info for patient's families
This document provides information about traumatic brain injury (TBI) for patients and families. It defines TBI as an injury to the brain caused by trauma to the skull. Common types of TBI are contusions, hemorrhages, and brain swelling. Management involves monitoring pressure and oxygen levels in the brain and using treatments like sedation, hypothermia, medications, and surgery to prevent further brain injury from swelling. The prognosis varies for each patient, but most experience worsening before improvement as the brain heals.
Status epilepticus infor for patients and families
Status epilepticus is defined as a seizure lasting more than 5 minutes or multiple seizures without regaining consciousness. It occurs due to abnormal electrical activity in the brain causing continuous seizures. Common causes include non-compliance with anti-seizure medications, infections, abnormalities in blood salts, drugs, strokes, cancer, and autoimmune diseases. To diagnose the underlying cause, patients will undergo tests like blood tests, CT/MRI scans of the brain, and lumbar punctures. Treatment involves identifying and treating the underlying cause, giving intravenous anti-seizure medications which may require sedation and ventilator support, and using EEGs to monitor seizure activity and guide medication adjustments.

Debate: Neurocritical Care Improves Outcomes in Severe TBI
Martin Smith and Mark Wilson debate whether neurocritical care improves outcomes in severe TBI.
Martin argues in favour of neurocritical care.
He concedes that longstanding and established practices are not as efficacious or innocuous as previously believed.
Very few specific interventions have been shown to improve outcomes in large randomised controlled trials. With the possible exception of avoidance of hypotension and hypoxaemia, most are based on analysis of physiology and pathophysiology.
Further, the substantial temporal and regional pathophysiological heterogeneity after TBI means that some interventions may be ineffective, unnecessary, or even harmful in certain patients at certain times.
Martin however, contends that improved understanding of pathophysiology and advances in neuromonitoring and imaging techniques have led to more effective and individualised treatment strategies. Ultimately, this has led to improved outcomes for patients.
In particular, the sole goal of identifying and treating intracranial hypertension has been superseded by a focus on the prevention of secondary brain insults. This is done by using a systematic, stepwise approach to maintenance of adequate cerebral perfusion and oxygenation.
Similarly, multimodal neuromonitoring also gives clinicians confidence to withhold potentially dangerous therapy. Particuarly in those with no evidence of brain ischemia/hypoxia or metabolic disturbance.
Mark Wilson on the other hand argues there is no benefit in neurocritical care following severe TBI.
The New England Journal of Medicine has published several articles that demonstrate no benefit from classic neurotrauma interventions (ICP monitoring, cooling, decompression). This is because factors such as ICP and CPP associate with bad outcomes by association rather than causation.
This debate will demonstrate that critical care just complicates things. Evidently, it is high time for the randomised trial between the very best neurocritical care and NOB therapy (Naso-pharyngeal, Oxygen and a Blanket).
Join Martin and Mark as they discuss the pros and cons of neurocritical care in the management of severe TBI.

Cerebrovascular disease / KFU- 2.1
A 62-year-old man experienced a temporary episode of aphasia while giving a speech, as well as previous episodes of double vision. He had undergone mitral valve replacement two years prior and was being treated with anticoagulants. The episodes were likely caused by small pieces of thrombus breaking off from his prosthetic heart valve and blocking blood flow to parts of his brain (TIAs). Insufficient anticoagulation treatment likely led to the formation of the thrombi. The aphasia was caused by disruption of blood flow to the language processing areas of his left brain.

Nursing management with cva patient
A cerebrovascular accident (CVA), also known as a stroke, is caused by disrupted blood flow to the brain resulting in the death of brain cells. There are two main types of strokes: ischemic strokes caused by blood clot blockages and hemorrhagic strokes caused by ruptured blood vessels. Treatment depends on the stroke type and may include clot-busting drugs, surgery, or controlling bleeding. Nursing care focuses on rehabilitation and prevention of complications through careful monitoring, positioning, and facilitating recovery of motor and cognitive functions. Lifestyle changes and medication can help prevent future strokes by managing risk factors like high blood pressure, smoking, obesity, and atrial fibrillation.
brain disorders.pdf
CT scans can be used to diagnose several brain disorders:
- Seizures may be caused by abnormalities visible on CT scans, such as low-density areas indicating injuries. CT scans are also used to diagnose concussions by revealing bruising or bleeding in the brain. Meningitis can cause swelling visible on CT scans. Strokes appear as ischemic or hemorrhagic areas that differ between CT and MRI scans. Hydrocephalus enlarges ventricles visible on CT or MRI scans. Parkinson's and Alzheimer's involve degeneration that cannot be seen directly but may be suggested on scans.

Bengin intracranial hypertension.pptx
Benign intracranial hypertension (BIH), also known as idiopathic intracranial hypertension or pseudotumor cerebri, is characterized by increased intracranial pressure without a tumor or other identifiable cause. Common symptoms include headache, nausea, visual disturbances, and papilledema which can cause vision loss if untreated. While the exact cause is unknown, theories include excess CSF production, increased blood flow to the brain, or impaired venous drainage from the brain. Treatment involves weight loss, medications like acetazolamide, and sometimes surgical procedures to relieve pressure like optic nerve sheath fenestration or CSF shunting.
begnin intracranial hypertension.pptx
Benign intracranial hypertension (BIH), also known as idiopathic intracranial hypertension or pseudotumor cerebri, is characterized by increased intracranial pressure without a tumor or other identifiable cause. Common symptoms include headache, nausea, visual disturbances, and papilledema which can cause vision loss if untreated. While the exact cause is unknown, theories include excess CSF production, increased blood flow to the brain, or impaired venous drainage from the brain. Treatment involves weight loss, medications like acetazolamide, and sometimes surgical procedures to relieve pressure like optic nerve sheath fenestration or CSF shunting.
Cva (cerebro vascular accident)
CVA (cerebrovascular accident), also known as stroke, and TIA (transient ischemic attack) are disruptions in blood flow to the brain. A CVA is caused by ischemia or hemorrhage in the brain and results in cell death, while a TIA's disruption is temporary without cell death. Risk factors include atherosclerosis, hypertension, cardiac issues, and diabetes. Symptoms depend on the location and size of the affected area but may include paralysis, impaired speech/vision, and sensory changes. Treatment focuses on prevention by controlling risk factors and potentially using blood thinners. Nursing care revolves around monitoring for complications and maximizing recovery of functions.
Anoxic brain injury and braindeath info for patient's families
This document discusses anoxic brain injury caused by cardiac arrest. It defines anoxic brain injury as occurring when the brain does not receive enough oxygen, usually after the heart stops pumping. It outlines that the brain can become irreversibly damaged after only 4 minutes without blood supply. The document describes how clinicians use tests such as CT scans and those measuring brain electrical activity to determine the severity of brain damage following cardiac arrest. It also explains that the prognosis for most patients is poor, with predictors being older age, multiple pre-existing diseases, a long duration of cardiac arrest, and an unwitnessed cardiac arrest.

Cerebral venous sinus thrombosis
This document describes a case of cerebral venous thrombosis (CVT) in a 20-year-old female patient who presented with worsening headache, nausea, dizziness, and blurred vision. It provides details on her medical history, physical exam findings, lab and imaging results. CVT is an uncommon type of stroke more common in young individuals. Risk factors include genetic thrombophilias, acquired conditions like pregnancy/puerperium and cancer. Clinical symptoms vary depending on increased intracranial pressure or focal brain injury. Management involves anticoagulation to stop thrombotic process along with supportive care. Outcomes range from full recovery in 80% of patients to mortality in 6-20% depending on severity of presentation
neurological disoder and sign symptoms causes
The document discusses neurological disorders and provides details about cerebrovascular accidents (strokes). It describes the blood supply to the brain from arteries like the internal carotid and vertebral arteries. There are two main types of strokes - ischemic caused by blockage and hemorrhagic caused by bleeding. Symptoms can include weakness, difficulty speaking, and vision issues. Diagnosis involves scans and tests of the blood. Treatment depends on the type but may include clot-busting drugs or surgery. Lifestyle changes can help prevent strokes by maintaining healthy blood pressure and cholesterol levels.
Management of head injury
This document provides an overview of the management of head injuries. It defines head injury as damage to the head from impact and classifies injuries as closed or open, diffuse or focal. The pathophysiology section explains how small increases in intracranial volume can raise pressure dramatically. Presentation may include altered consciousness, bleeding, seizures or vomiting. Investigations include CT scans to detect fractures or bleeds. Treatment focuses on preventing secondary injuries like hypoxia, controlling pressure, and maintaining perfusion and nutrition. Follow-up is needed as some patients with mild injuries may later develop complications.
Idiopathic Intracranial Hypertension
This document provides information about idiopathic intracranial hypertension (IIH), including its symptoms, pathophysiology, risk factors, diagnosis, and treatment. IIH is characterized by increased intracranial pressure without a tumor or other identifiable cause. Common symptoms include headache, nausea, visual disturbances, and papilledema. The main risk factors are obesity, particularly in women of childbearing age. The cause is unknown but may involve increased cerebrospinal fluid production or impaired cerebral venous drainage. Diagnosis involves evaluating signs and symptoms of increased intracranial pressure and ruling out other potential causes through imaging and lumbar puncture.
Stroke
This document provides information about strokes, including types, symptoms, risk factors, diagnosis, and treatment. It discusses the two main types of strokes: ischemic, caused by blockage of blood vessels in the brain, and hemorrhagic, caused by bleeding in the brain. Symptoms of stroke can include weakness, numbness, vision problems, dizziness, and confusion. Risk factors include age, high blood pressure, atrial fibrillation, diabetes, smoking, obesity, and family history. Diagnosis involves physical exams, imaging tests like CT scans and MRIs, and blood tests. Treatment focuses on preventing future strokes through medications like blood thinners, statins, and blood pressure medications as well as rehabilitation therapies.
Intracranial bleeding
Intracranial bleeding encompasses all bleeds that may occur within the cranial cavity including Epidural, Subdural, Sub arachnoid, intraparenchymal and Intraventricular haemorrhages. all are discussed in these slides and relevant references are provided for detailed information.
It is important to note that medicine is not learnt online but through series of organised events under specialised supervision in recognised institutions of learning.
Intracerebral Hemorrhage - Classification, Clinical symptoms, Diagnostics
An intracerebral hemorrhage occurs when a blood vessel ruptures within the brain tissue, causing blood to accumulate and form a hematoma. The most common causes are hypertension, brain aneurysms, and head trauma. Symptoms include sudden severe headache, vomiting, weakness, and loss of consciousness. Diagnosis is typically made through CT scan or MRI, which show the location and size of the hemorrhage. Treatment aims to control blood pressure, reduce swelling, and in some cases surgically remove the blood clot. Complications can include neurological deficits, seizures, and death, with mortality rates around 50% within one month.
CVA BY DR.Manoj.pptx
Cerebrovascular Accident or stroke is defined as an abrupt onset of neurological deficit caused by a focal vascular issue. Stroke is the second leading cause of death worldwide. The clinical manifestations of stroke can vary widely due to the complex anatomy of the brain and vasculature. Imaging such as CT and MRI are used to determine if the cause is ischemia or hemorrhage. Treatment focuses on rapid evaluation, managing risk factors, IV thrombolysis if appropriate, and rehabilitation to prevent complications and encourage recovery.
C.08a-Diagnosis-and-Treatment-of-Acute-Ischemic-Stroke-Presentation-ppt.pptx
1. The document discusses the diagnosis and treatment of acute ischemic stroke. It outlines the time windows for treatment with intravenous thrombolysis, which is most effective within 4.5 hours of symptom onset.
2. Early diagnosis is critical in stroke care due to the concept of "time is brain". Delays in treatment can lead to further neuronal damage and worse outcomes. The goals are to perform a CT scan within 20 minutes of arrival and initiate thrombolysis within 60 minutes.
3. Post-thrombolytic management focuses on monitoring for hemorrhagic complications and providing supportive care to reduce disability from the stroke.

Hypertension, also known as high blood pressure, is a serious medical condition that occurs when blood pressure in the body's arteries is consistently too high. Blood pressure is the force of blood pushing against the walls of blood vessels as the heart pumps it. Hypertension can increase the risk of heart disease, brain disease, kidney disease, and premature death.

FACIAL NERVE
The facial nerve, also known as cranial nerve VII, is one of the 12 cranial nerves originating from the brain. It's a mixed nerve, meaning it contains both sensory and motor fibres, and it plays a crucial role in controlling various facial muscles, as well as conveying sensory information from the taste buds on the anterior two-thirds of the tongue.

留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径，但认证只是个体行为，不是所有留学生都操作，所以没有办理认证的留学生的学历在国内也是查询不到的，他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单，就有了使用价值。

This particular slides consist of- what is hypotension,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.

- 6. Outline Definition Etiologies Diagnosis Imaging Management Prognosis Treatment Establish a cause •High blood pressure is the most common cause but some patients may need further tests Medical treatment •Blood pressure control – we use medications to control the BP to prevent another bleed •Ensure the patient’s blood is not thin •Often, we need to sedate patients with medications to allow the brain to heal •If patient’s are sedated then we assist their breathing with a machine (ventilator) Surgery •Surgery may be required but also comes with risks
- 7. Outline Definition Etiologies Diagnosis Imaging Management Prognosis Prognosis Predicting an outcome can be difficult, however, certain factors may help Factors associated with a bad outcome: •Older age •Previous multiple diseases (diabetes, kidney disease, heart disease, strokes etc) •Previous dependant functioning •Size of the original bleed •Decreased level of consciousness after the bleed •Location of the bleed •If the bleed occurs in vital areas of the brain, the outcome is usually worse
