Traumatic Subarachnoid Hemorrhage (tSAH), caused by a blow to the head, has characteristics that set it apart from other types of traumatic bleeding. If the bleeding is minor and isolated, the prognosis is excellent, and treatment is primarily conservative. However, if it is accompanied by severe brain injury or delayed complications—such as cerebral vasospasm or hydrocephalus—the condition can rapidly deteriorate, leading to a poor prognosis.This article explains the principles of conservative treatment for tSAH and why surgical interventions, such as V-P Shunting, are necessary in severe cases. We also focus on the risk of delayed hydrocephalus, which can manifest as cognitive impairment or gait disturbance (Hakim’s Triad) long after the initial injury.

Following a blow to the head, the greatest threat to life is traumatic intracranial hemorrhage—bleeding that occurs between the skull and the brain. Acute Epidural Hematoma (EDH) and Acute Subdural Hematoma (ASH) are particularly urgent conditions. Their degree of emergency and prognosis differ significantly depending on the site of occurrence, the source of bleeding, and the shape of the hematoma on CT scans (e.g., lenticular vs. crescentic).This article provides a comprehensive comparison of EDH, ASH, and Traumatic Subarachnoid Hemorrhage (tSAH)based on their causes, imaging findings, and outlooks. Understanding the risks of brain herniation and complications like delayed vasospasm is essential for rapid diagnosis and appropriate treatment.

Cerebral contusions and traumatic intracerebral hematomas, where the brain tissue itself is damaged by a strong impact, are life-threatening emergencies that profoundly affect a patient's future. Treatment proceeds according to the severity of the injury, evaluated using the Glasgow Coma Scale (GCS). Depending on the size of the hematoma, emergency surgery may be mandatory.This article focuses on direct brain tissue injuries, detailing GCS-based treatment principles and surgical indications. Furthermore, we discuss the practicalities of the Japanese medical fee system regarding rehabilitation time limits and the prognosis of long-term aftereffects, such as Higher Brain Function Disorders.

A strong impact to the head should never be dismissed as "just a bump." If the brain itself is damaged or if bleeding (hematoma) occurs between the membranes covering the brain, it can escalate into a life-threatening situation.This article explains the major diagnoses resulting from head trauma, categorized into "Direct Damage to Brain Tissue"and "Bleeding Between the Brain Membranes." We also cover critical warning signs and why immediate medical attention is necessary—especially for conditions like Chronic Subdural Hematoma, where symptoms may not appear until weeks or even months after the initial injury.

When you open X, you might occasionally encounter a timeline that won't update or see errors like "Tweets aren't loading" or "Something went wrong." While these can be caused by X’s own system outages, they are very often the result of your connection environment or accumulated data within the app.In this article, we identify the specific causes behind loading errors and provide a step-by-step guide to emergency solutions—including clearing app cache and reviewing connection settings. Use this manual to get your X experience back to normal.

Have you ever tried to open X (formerly Twitter) only to be met with a "Cannot Log In" message or an error even after entering your password? The causes range from simple "input errors" to serious issues like "Account Suspension" or "Hijacking."In this article, we categorize login issues by their cause—passwords, systems, or account status—and provide detailed emergency countermeasures and recovery steps for each. We also share preventive measures to ensure you never lose access again. Use this guide to regain control of your X account.

One day, you open X only to find your account has been suspended. A "Suspension" occurs when X determines that an account has violated its Terms of Service or Policies. In many cases, this happens without prior warning. Causes range from "Spam" and "Rule Violations" to "Security Compromises."In this article, we categorize the specific causes of account suspension and provide a detailed guide on the "Appeals Process" to restore your account. We also outline concrete prevention strategies to ensure you can use X safely and avoid future penalties.

Having your X account hacked can lead to severe consequences, including the leak of personal information and your account being used to spread spam or scams. While there are many ways hackers gain access, the most common culprits are "password leaks" or the "misuse of third-party apps."In this article, we explain the specific methods hackers use, provide an emergency action plan if you suspect a compromise, and outline the definitive prevention steps to protect your account. Review your security settings now to ensure your safety on X.

Are you tired of receiving spam, solicitations, or offensive Direct Messages (DMs) from unknown accounts on X? The primary reason for most annoying DMs is that your settings are accidentally set to "Allow messages from everyone."In this article, we explain the root causes of DM spam and provide a step-by-step guide to reclaiming your inbox—from adjusting your core privacy settings to using "Block" and "Report" features to permanently exclude malicious users. Stop the annoying notifications and enjoy a cleaner X experience today.

The "Something went wrong" message on X can be incredibly frustrating, as it often prevents you from viewing tweets or performing any actions.This error can stem from a variety of sources—ranging from simple temporary system glitches to more serious cases like account restrictions or shadowbans. In this article, we identify the two main categories of this error and provide a step-by-step action plan, from basic "System Refreshes" to "Professional Account Recovery" methods.
