Symptoms And Signs

Concussion is a form of mild traumatic brain injury (mTBI) that can occur as a result of contact to the head or other parts of the body that causes a rapid acceleration-deceleration force to the brain that may cause a functional disturbance in an individual’s ability to concentrate or learn new information. Contrary to popular belief, it is not a bruise to the brain, and there is usually nothing detectable on standard imaging such as a computed tomography or magnetic resonance imaging. Symptoms and signs are therefore important to detect and include decreased levels of consciousness, headache, nausea, difficulty concentrating, memory loss, and poor coordination. These signs and symptoms usually occur within minutes after the injury but may also appear several hours or even days later.

Symptoms And Signs

Background Recently, a clinical classification system was described to determine whether symptoms and signs of patients presenting with a first episode suggestive of multiple sclerosis (MS) indicate the presence of monofocal or multifocal disease. Objectives To evaluate the value of this new classification system by comparing the results with those of simultaneously obtained magnetic resonance imaging (MRI) scans. Methods The 487 patients, randomised in the BENEFIT study, were centrally assessed using the new system and classified as monofocal or multifocal, based on clinical information by two neurologists masked for the MRI results. MRI analyses were performed by expert readers masked for the clinical classification. Results Patients classified as multifocal had more T2 hyperintense (median: 21 versus 15.5) and more T1 hypo-intense lesions (median: 2 versus 1) than those classified as monofocal. Patients classified at the local site as having evidence of a single clinical lesion, but reclassified centrally as having a clinical multifocal central nervous system presentation, had more T2 lesions than monofocal patients. In addition, patients with a multifocal presentation more often fulfilled the MRI criteria for dissemination in space, as incorporated in the International Panel (IP) diagnostic criteria for MS. Conclusion These data provide justification for the recently proposed clinical classification system to be used in patients who present with a first episode suggestive of MS, in that `multifocal', based on symptoms and signs, is associated with more lesions on MRI.

Mansonic neuroschistosomiasis (MN) is not only the most common but also the most serious ectopic presentation of the infection by Schistosoma mansoni. Both, brain and spinal cord can be independently affected by the infection, but the later is more frequently affected. Brain MN by itself is due to the presence of eggs and/or adult worms in situ and can be symptomatic or asymptomatic. Unlike the brain MN, spinal cord mansonic neuroschistosomiasis is more frequently symptomatic. In both forms the intensity, the seriousness and also the clinical characteristics of signs and symptoms depend on the amount of eggs in the compromised region and on the intensity of the inflammatory reaction surrounding the eggs. Cerebrospinal fluid examination and magnetic resonance imaging are important diagnostic tools. Both corticosteroids and drugs against S. mansoni are used in the treatment. The outcome may largely depend upon the prompt use of these drugs.

Optic Nerve Drusen

With the introduction and development of new diagnostic techniques, the relevance of drusen of the optic nerve di-agnostics is increasing. Existing imaging techniques alone or in their various combinations cannot allow to confirm optic nerve drusen in all clinical cases. The diagnosis of optic nerve drusen causes some difficulties because of absence of clear diagnostic standards and classification. Since the advent of new ophthalmological methods of structural and topographic visual analysis evaluation, such as spectral-domain optical coherence tomography, Heidelberg retina tomography, videooculography, B-scan ultrasonography of the orbits and optic nerve, fluorescent angiography of the retina, computed tomography and magnetic resonance imaging of the brain and orbits, the diagnostics of optic nerve drusen becomes more informative. In this article we review the main current imaging techniques in the diagnostics of the optic nerve drusen.

Background: Until the 70s, cerebrovascular diseases (CVDs) were neglected to the lack of resources. However, due to the advancement of technology, several imaging tests have appeared, such as magnetic resonance and computed tomography, which facilitated the diagnosis and the understanding of the pathophysiology of each disease. Objectives: The objective of this work is to identify the main CVDs signs and symptoms. Methods: An integrative literature review was carried out based on selected articles from Google Scholar, PubMed and SciELO, using the terms headache, cerebrovascular disease, neurology. Results: CVDs are characterized by causing damage to brain vessels, due to changes in blood flow momentarily or permanently in an area of the brain, allowing them to be classified as ischemic or hemorrhagic. In ischemic there is a blockage of blood flow and, consequently, of oxygen to areas of the brain, in hemorrhagic rupture of a vessel occurs and, with this, blood leakage. Therefore, it is necessary to recognize the signs and symptoms early, in order to prevent loss of neurological function, movements on one side of the body and the presence or absence of headaches in both patients, with ischemic CVD and hemorrhagic CVD prevent rapid loss of consciousness accompanied by severe headache. Such signs and symptoms associated with the patient’s family history and lifestyle can help in the diagnosis of this disease. Conclusion: Therefore, it is important to recognize the signs and symptoms of CVDs, in order to determine the treatment and advise the patient, which will guarantee a better prognosis.
