Recognizing early signs changes the course of the disease.<\/pee>\n<\/header>\n<div class=\"container\">\n<div class=\"intro-paragraph\">\nParkinson&#8217;s disease affects 200,000 people in France and 10 million worldwide. It is often associated with tremors \u2014 but this is a misleading simplification: 25% of Parkinson&#8217;s patients never have tremors. Even more surprisingly, the precursors of the disease appear 10 to 20 years before the first motor symptoms \u2014 smell disorders, constipation, sleep disorders. Understanding Parkinson&#8217;s in its entirety \u2014 motor AND non-motor \u2014 is the key to early diagnosis and effective support.\n<\/div>\n<div class=\"stats-grid\">\n<div class=\"stat-card\"><span class=\"stat-number\">200,000<\/span><\/p>\n<div class=\"stat-label\">people affected in France \u2014 2nd neurodegenerative disease after Alzheimer&#8217;s<\/div>\n<\/div>\n<div class=\"stat-card\"><span class=\"stat-number\">10\u201320 years<\/span><\/p>\n<div class=\"stat-label\">before the first motor symptoms, precursor signs may be present<\/div>\n<\/div>\n<div class=\"stat-card\"><span class=\"stat-number\">30\u201350%<\/span><\/p>\n<div class=\"stat-label\">develop significant cognitive disorders during the disease<\/div>\n<\/div>\n<\/div>\n<h2>1. Mechanism: the loss of dopamine<\/h2>\n<pee>Parkinson&#8217;s is caused by the <strong>progressive degeneration of dopaminergic neurons<\/strong> in the <em>substantia nigra<\/em> (substantia nigra) in the midbrain. These neurons produce dopamine \u2014 a neurotransmitter essential for controlling voluntary movements, motivation, and emotional regulation. When 50 to 60% of these neurons are destroyed, motor symptoms appear. This loss is accompanied by the accumulation of Lewy bodies (aggregates of alpha-synuclein protein) in the surviving neurons.<\/pee>\n<h2>2. The motor triad<\/h2>\n<div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\ud83d\udc22 Mandatory cardinal sign<\/div>\n<h4>Bradykinesia \u2014 slowness of movements<\/h4>\n<pee>Bradykinesia is the only mandatory cardinal sign for diagnosing Parkinson&#8217;s. It manifests as a general slowness of movements, a decrease in their amplitude (small steps, small writing \u2014 micrographia), and difficulty initiating movement (&#8220;feet glued to the ground&#8221;). It directly impacts all daily activities: dressing, eating, walking.<\/pee>\n<\/div>\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83e\udef4 Resting tremor<\/div>\n<h4>The tremor \u2014 signature but not mandatory<\/h4>\n<pee>The typical Parkinsonian tremor is a <strong>resting tremor<\/strong> (it disappears during intentional movement), at a frequency of 4 to 6 Hz, often asymmetrical at first (predominates on one side). The so-called &#8220;pill-rolling&#8221; movement (rolling the thumb on the index finger as if rolling a pill) is characteristic. But 25% of Parkinson&#8217;s patients do not have a visible tremor.<\/pee>\n<\/div>\n<div class=\"method-card rose\">\n<div class=\"method-badge badge-rose\">\ud83d\udcaa Muscle rigidity<\/div>\n<h4>Rigidity \u2014 resistance to mobilization<\/h4>\n<pee>Parkinsonian rigidity is characterized by resistance to passive movements, present throughout the joint range. Two types are described: <strong>cogwheel rigidity<\/strong> (intermittent resistance, characteristic of Parkinson&#8217;s) and <strong>lead-pipe rigidity<\/strong> (uniform and continuous resistance). It is a source of muscle pain and early muscle fatigue.<\/pee>\n<\/div>\n<h2>3. Non-motor symptoms: precursor signs<\/h2>\n<pee>Non-motor symptoms are now recognized as appearing well before motor signs \u2014 sometimes 10 to 20 years before diagnosis. They constitute what is called the &#8220;prodromal phase&#8221; of Parkinson&#8217;s. Recognizing these signals can allow for earlier diagnosis and intervention.<\/pee>\n<table class=\"comparison-table\">\n<thead>\n<tr>\n<th>Non-motor symptom<\/th>\n<th>Frequency<\/th>\n<th>Precedes motor signs?<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Anosmia<\/strong> (loss of smell)<\/td>\n<td>90%<\/td>\n<td>Yes \u2014 5-10 years before<\/td>\n<\/tr>\n<tr>\n<td><strong>RBD<\/strong> (REM sleep behavior disorder)<\/td>\n<td>50-60%<\/td>\n<td>Yes \u2014 may precede by 15-20 years<\/td>\n<\/tr>\n<tr>\n<td><strong>Chronic constipation<\/strong><\/td>\n<td>80%<\/td>\n<td>Yes \u2014 several years before<\/td>\n<\/tr>\n<tr>\n<td><strong>Depression<\/strong><\/td>\n<td>30-40%<\/td>\n<td>Often<\/td>\n<\/tr>\n<tr>\n<td><strong>Cognitive disorders<\/strong><\/td>\n<td>30-50%<\/td>\n<td>May precede motor signs<\/td>\n<\/tr>\n<tr>\n<td><strong>Pain<\/strong><\/td>\n<td>40-50%<\/td>\n<td>Sometimes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>4. Cognitive disorders in Parkinson&#8217;s<\/h2>\n<pee>30 to 50% of patients develop significant cognitive disorders. The most affected areas are <strong>executive functions<\/strong> (planning, mental flexibility), <strong>processing speed<\/strong> (bradyphrenia), <strong>divided attention<\/strong>, and <strong>working memory<\/strong>. These disorders, often minimized by the patients themselves, deeply impact autonomy and quality of life.

Recognizing early signs changes the course of the disease.<\/p>\n<\/header>\n<div class=\"container\">\n<div class=\"intro-paragraph\">\nParkinson's disease affects 200,000 people in France and 10 million worldwide. It is often associated with tremors \u2014 but this is a misleading simplification: 25% of Parkinson's patients never have tremors. Even more surprisingly, the precursors of the disease appear 10 to 20 years before the first motor symptoms \u2014 smell disorders, constipation, sleep disorders. Understanding Parkinson's in its entirety \u2014 motor AND non-motor \u2014 is the key to early diagnosis and effective support.\n<\/div>\n<div class=\"stats-grid\">\n<div class=\"stat-card\"><span class=\"stat-number\">200,000<\/span><div class=\"stat-label\">people affected in France \u2014 2nd neurodegenerative disease after Alzheimer's<\/div><\/div>\n<div class=\"stat-card\"><span class=\"stat-number\">10\u201320 years<\/span><div class=\"stat-label\">before the first motor symptoms, precursor signs may be present<\/div><\/div>\n<div class=\"stat-card\"><span class=\"stat-number\">30\u201350%<\/span><div class=\"stat-label\">develop significant cognitive disorders during the disease<\/div><\/div>\n<\/div>\n\n<h2>1. Mechanism: the loss of dopamine<\/h2>\n<p>Parkinson's is caused by the <strong>progressive degeneration of dopaminergic neurons<\/strong> in the <em>substantia nigra<\/em> (substantia nigra) in the midbrain. These neurons produce dopamine \u2014 a neurotransmitter essential for controlling voluntary movements, motivation, and emotional regulation. When 50 to 60% of these neurons are destroyed, motor symptoms appear. This loss is accompanied by the accumulation of Lewy bodies (aggregates of alpha-synuclein protein) in the surviving neurons.<\/p>\n\n<h2>2. The motor triad<\/h2>\n\n<div class=\"method-card blue\">\n<div class=\"method-badge badge-blue\">\ud83d\udc22 Mandatory cardinal sign<\/div>\n<h4>Bradykinesia \u2014 slowness of movements<\/h4>\n<p>Bradykinesia is the only mandatory cardinal sign for diagnosing Parkinson's. It manifests as a general slowness of movements, a decrease in their amplitude (small steps, small writing \u2014 micrographia), and difficulty initiating movement (\"feet glued to the ground\"). It directly impacts all daily activities: dressing, eating, walking.<\/p>\n<\/div>\n\n<div class=\"method-card teal\">\n<div class=\"method-badge badge-green\">\ud83e\udef4 Resting tremor<\/div>\n<h4>The tremor \u2014 signature but not mandatory<\/h4>\n<p>The typical Parkinsonian tremor is a <strong>resting tremor<\/strong> (it disappears during intentional movement), at a frequency of 4 to 6 Hz, often asymmetrical at first (predominates on one side). The so-called \"pill-rolling\" movement (rolling the thumb on the index finger as if rolling a pill) is characteristic. But 25% of Parkinson's patients do not have a visible tremor.<\/p>\n<\/div>\n\n<div class=\"method-card rose\">\n<div class=\"method-badge badge-rose\">\ud83d\udcaa Muscle rigidity<\/div>\n<h4>Rigidity \u2014 resistance to mobilization<\/h4>\n<p>Parkinsonian rigidity is characterized by resistance to passive movements, present throughout the joint range. Two types are described: <strong>cogwheel rigidity<\/strong> (intermittent resistance, characteristic of Parkinson's) and <strong>lead-pipe rigidity<\/strong> (uniform and continuous resistance). It is a source of muscle pain and early muscle fatigue.<\/p>\n<\/div>\n\n<h2>3. Non-motor symptoms: precursor signs<\/h2>\n<p>Non-motor symptoms are now recognized as appearing well before motor signs \u2014 sometimes 10 to 20 years before diagnosis. They constitute what is called the \"prodromal phase\" of Parkinson's. Recognizing these signals can allow for earlier diagnosis and intervention.<\/p>\n\n<table class=\"comparison-table\">\n<thead><tr><th>Non-motor symptom<\/th><th>Frequency<\/th><th>Precedes motor signs?<\/th><\/tr><\/thead>\n<tbody>\n<tr><td><strong>Anosmia<\/strong> (loss of smell)<\/td><td>90%<\/td><td>Yes \u2014 5-10 years before<\/td><\/tr>\n<tr><td><strong>RBD<\/strong> (REM sleep behavior disorder)<\/td><td>50-60%<\/td><td>Yes \u2014 may precede by 15-20 years<\/td><\/tr>\n<tr><td><strong>Chronic constipation<\/strong><\/td><td>80%<\/td><td>Yes \u2014 several years before<\/td><\/tr>\n<tr><td><strong>Depression<\/strong><\/td><td>30-40%<\/td><td>Often<\/td><\/tr>\n<tr><td><strong>Cognitive disorders<\/strong><\/td><td>30-50%<\/td><td>May precede motor signs<\/td><\/tr>\n<tr><td><strong>Pain<\/strong><\/td><td>40-50%<\/td><td>Sometimes<\/td><\/tr>\n<\/tbody>\n<\/table>\n\n<h2>4. Cognitive disorders in Parkinson's<\/h2>\n<p>30 to 50% of patients develop significant cognitive disorders. The most affected areas are <strong>executive functions<\/strong> (planning, mental flexibility), <strong>processing speed<\/strong> (bradyphrenia), <strong>divided attention<\/strong>, and <strong>working memory<\/strong>. These disorders, often minimized by the patients themselves, deeply impact autonomy and quality of life. Regular cognitive stimulation is recommended to maintain preserved functions as long as possible.<\/p>\n\n<div class=\"program-card\">\n<h4>\ud83e\udde0 DYNSEO support for Parkinson's<\/h4>\n<p>\u2022 <a href=\"https:\/\/www.dynseo.com\/courses\/comprendre-la-maladie-de-parkinson-guide-essentiel-pour-les-proches\/\" target=\"_blank\"><strong>Training \"Understanding Parkinson's Disease\"<\/strong><\/a> \u2014 guide for relatives<br>\n\u2022 <a href=\"https:\/\/www.dynseo.com\/courses\/parkinson-en-etablissement-comprendre-la-maladie-et-adapter-sa-pratique-professionnelle\/\" target=\"_blank\"><strong>Training \"Parkinson's in institutions\"<\/strong><\/a><br>\n\u2022 <a href=\"https:\/\/www.dynseo.com\/test-concentration-attention\/\" target=\"_blank\"><strong>Concentration and Attention Test<\/strong><\/a> \u2014 assess cognitive functions<br>\n\u2022 <a href=\"https:\/\/www.dynseo.com\/nos-outils\/\" target=\"_blank\"><strong>62 cognitive stimulation tools<\/strong><\/a><\/p>\n<a href=\"https:\/\/www.dynseo.com\/courses\/comprendre-la-maladie-de-parkinson-guide-essentiel-pour-les-proches\/\" target=\"_blank\" class=\"cta-button\">Discover Parkinson's training \u2192<\/a>\n<\/div>\n\n<h2>FAQ<\/h2>\n<div class=\"faq-item\"><h4>What is Parkinson's disease?<\/h4><p>Neurodegenerative disease caused by the loss of dopaminergic neurons in the substantia nigra. 2nd neurodegenerative disease, affecting 200,000 people in France.<\/p><\/div>\n<div class=\"faq-item\"><h4>What are the 3 cardinal signs?<\/h4><p>Bradykinesia (mandatory), resting tremor, and muscle rigidity.
