Have you ever experienced Instagram suddenly crashing, the timeline failing to update, or Stories feeling sluggish? While these issues can sometimes be caused by Instagram's own servers, they are more often the result of device settings, accumulated data, or your connection environment.In this article, we identify the specific causes of Instagram glitches and provide a step-by-step "Emergency Response Guide." From clearing app cache to improving connectivity and long-term prevention, use this manual to get your Instagram back to peak performance.

It is incredibly stressful when you open Instagram only to find you’ve been locked out or keep receiving error messages despite entering your password. Login failures range from simple "credential errors" to "account disabling (bans)" and even "account hijacking."In this article, we categorize Instagram login issues into three patterns and provide detailed recovery steps for each. We also include definitive preventive measures to help you regain your account and keep it secure for the future.

Even though they share the same name, "Subarachnoid Hemorrhage," the traumatic (tSAH) and non-traumatic (aneurysmal rupture) types differ significantly in cause, symptom severity, and urgency.Non-traumatic cases often present with the "worst headache of your life" and require immediate surgery to secure a ruptured aneurysm, carrying a high mortality rate. In contrast, tSAH is caused by physical trauma, often involves minor bleeding, and is typically managed conservatively. This article compares the two based on the source of bleeding, CT scan patterns, re-bleeding risks, and the necessity of emergency surgery.

If you experience a "blackout" or "loss of consciousness" (LOC) following a blow to the head, it is often a sign of a severe brain injury. While an isolated, minor Traumatic Subarachnoid Hemorrhage (tSAH) rarely causes a total loss of consciousness on its own, its presence suggests that the head sustained an impact powerful enough to cause dangerous complications like cerebral contusions or acute subdural hematomas.This article explains the exact mechanisms behind losing consciousness in the context of tSAH. Behind such an event, there is usually a rapid spike in intracranial pressure or a concurrent severe brain injury. If you lose consciousness—even briefly—it is critical to seek immediate neurosurgical evaluation to prevent life-threatening events like brain herniation.

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.
