With the right knowledge and the right support, it is possible to find ways to regain quality of life.<\/strong><\/p><h2>What is peripheral neuropathy?<\/h2><p>Imagine your nervous system as a <strong>vast communications network<\/strong>. The brain and spinal cord function as the main centre, while the peripheral nerves are the cables that carry messages throughout the body.<\/p><p>Peripheral neuropathy arises when these \u201ccables\u201d become damaged. As a result, communication between the brain and the rest of the body is compromised - messages arrive distorted, incomplete, or simply not at all.<\/p><p>This condition can affect nerves <strong>sensory<\/strong> (responsible for sensations such as pain and temperature), <strong>motors<\/strong> (which control movement) and <strong>autonomous<\/strong> (which regulate involuntary functions). Prevalence increases significantly with age and can reach up to <strong>30%<\/strong> of people after the age of 70.<\/p><h2>What causes peripheral neuropathy?<\/h2><p>Peripheral neuropathy <strong>rarely comes out of nowhere<\/strong>. In most cases, there is an underlying cause, and identifying it is the first step towards effective treatment.<\/p><p>A <strong>diabetes<\/strong> tops the list of causes in developed countries. High blood sugar levels progressively damage peripheral nerves, affecting more than half (<strong>&gt;50%<\/strong>) of people with diabetes throughout their lives.<\/p><p>The <strong>vitamin deficiencies<\/strong>, vitamins, particularly B-complex vitamins, also play an important role. These vitamins are essential for nerve health, and a lack of them can jeopardise nerve function.<\/p><p>Other common causes include <strong>autoimmune diseases<\/strong> (such as lupus or Guillain-Barr\u00e9 syndrome), <strong>infections<\/strong> (HIV, hepatitis C), <strong>trauma<\/strong> and <strong>exposure to toxic substances<\/strong>, including some chemotherapy drugs.<\/p><p><img decoding=\"async\" class=\"alignleft wp-image-6248\" src=\"https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico.webp\" alt=\"\" width=\"780\" height=\"520\" srcset=\"https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico.webp 1920w, https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico-300x200.webp 300w, https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico-1024x683.webp 1024w, https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico-768x512.webp 768w, https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico-1536x1024.webp 1536w, https:\/\/neuropsiquiatria.pt\/wp-content\/uploads\/2026\/04\/neuropatia-nervo-periferico-18x12.webp 18w\" sizes=\"(max-width: 780px) 100vw, 780px\" \/><\/p><h2>What are the symptoms of peripheral neuropathy?<\/h2><p>Symptoms usually set in <strong>gradually<\/strong>, typically starting at the toes and slowly progressing towards the torso.<\/p><p>The most common manifestations include <strong>tingling<\/strong>, <strong>dormancy<\/strong> e <strong><a href=\"https:\/\/neuropsiquiatria.pt\/en\/dor-neuropatica\/\">neuropathic pain<\/a><\/strong> - often described as <strong>burning<\/strong>, <strong>electric shock<\/strong> or <strong>needles<\/strong>. <strong>Many people report that the pain gets worse at night, disturbing their sleep<\/strong>.<\/p><p>As the condition progresses, motor changes can appear: <strong>muscle weakness<\/strong>, <strong>difficulty walking<\/strong>, <strong>frequent cramps<\/strong> e <strong>balance problems<\/strong> - increasing the risk of falls.<\/p><p>When the autonomic nerves are affected, the following can occur <strong>changes in perspiration<\/strong>, <strong>digestive problems<\/strong> or <strong>variations in blood pressure<\/strong>.<\/p><p>If you recognise some of these symptoms, <strong>seek medical assessment<\/strong>.<\/p><p><strong>Early diagnosis really makes a difference<\/strong>.<\/p><h2>How is peripheral neuropathy treated?<\/h2><p>The treatment is based on two pillars: <strong>treat the underlying cause<\/strong> e <strong>relieve symptoms<\/strong>.<\/p><p>When there is a treatable cause - such as uncontrolled diabetes or vitamin deficiency - intervention can <strong>halting progress<\/strong> and, in some cases, allow significant recovery.

Keeping diabetes under control, avoiding excessive alcohol consumption and ensuring a balanced diet rich in B vitamins significantly reduces the risk.<\/p><h3>What tests are needed for diagnosis?<\/h3><p>Diagnosis is based on clinical assessment, complemented by <a href=\"https:\/\/www.tuasaude.com\/eletroneuromiografia\/\">electroneuromyography<\/a>\u00a0 (which assesses nerve conduction), blood tests and sometimes magnetic resonance imaging.<\/p><h3>Does physiotherapy help with peripheral neuropathy?<\/h3><p>Absolutely.
