In this video, I explain what SPG4 is, what its genetic cause is, and how it affects the nervous system over time. I show that SPG4 is a rare neurological genetic disease caused by alterations in a gene responsible for the proper maintenance of long motor neurons. These cells are fundamental for transmitting commands from the brain to the legs. When the mutation occurs, there is progressive degeneration of these pathways, leading to spasticity and difficulty walking. I explain the main symptoms of hereditary spastic paraparesis type 4, such as muscle stiffness, increased muscle tone, exaggerated reflexes, and progressive weakness in the legs. In many cases, the condition begins subtly, with frequent stumbling or a feeling of heavy legs, and progresses slowly. I also detail how SPG4 is diagnosed, which involves neurological clinical evaluation, imaging tests to rule out other causes, and confirmation by genetic testing. Correct identification of the mutation is fundamental for both the patient and family counseling. Throughout the video, I explain the difference between pure and complicated forms of hereditary spastic paraparesis and why SPG4 usually presents predominantly with motor impairment of the legs, without significant cognitive involvement. Finally, I organize the main points about SPG4: genetic cause, progression, symptoms, diagnosis, and the importance of multidisciplinary follow-up to maintain mobility and quality of life. ⏱️ Video Chapters: 00:00 - What is Hereditary Spastic Paraparesis Type 4? 02:18 - The Genetic Cause of SPG4 04:47 - How the Disease Affects the Nervous System 07:05 - Main Symptoms and Evolution 09:32 - How the Diagnosis is Made 11:48 - Difference Between Pure and Complicated Forms 13:30 - Management and Follow-up 🧩 In this video: Understand what Hereditary Spastic Paraparesis Type 4 is Discover the genetic cause of SPG4 Learn how to recognize the main symptoms See how the diagnosis and follow-up are done 🎯 Schedule Your Consultation With the Specialist Now (Online or In-Person)! https://bit.ly/drcaiobruzaca Hereditary Spastic Paraparesis Type 4 (SPG4)    • Paraparesia Espástica Hereditária tipo 4 (...
