As populations age worldwide, degenerative diseases are increasingly common. These progressive conditions gradually worsen neurological deficits and physical abilities, often leading to significant disability. In France, neurodegenerative disorders like Alzheimer's and Parkinson's predominantly affect older adults.
Degenerative diseases are chronic conditions that develop slowly, resulting in progressive physical, physiological, or mental impairments.
They encompass a range of serious disorders, including dementias (such as Alzheimer's), Parkinson's disease, multiple sclerosis, paraplegia, myopathies, myasthenia gravis, epilepsy, stroke, and other neurological conditions. Among these, neurodegenerative diseases—those causing nervous system deterioration—are the most recognized and prevalent.
The relentless health decline from these diseases profoundly impacts those affected, typically culminating in severe physical or mental handicaps.
Many degenerative diseases have genetic roots, making them hereditary. Others stem from prolonged exposure to toxins or biological agents over a lifetime.
While symptomatic relief is possible for some, most degenerative diseases remain incurable.
The most prevalent degenerative diseases linked to aging are Alzheimer's and Parkinson's.
Alzheimer's is a neurodegenerative form of dementia characterized by gradual brain damage and neuron death. Progression varies by individual.
Hallmark symptoms include worsening memory loss, cognitive decline, language difficulties, impaired motor skills, and disorientation with objects or people. This leads to major disruptions in daily life, eventual loss of independence, and the need for full-time care.
In France, around 1.2 million people live with Alzheimer's or related dementias, such as vascular dementia, Lewy body dementia, or frontotemporal degeneration. It is the leading dementia in seniors.
Parkinson's, another major neurodegenerative disease in older adults, typically onset around age 58. It affects about 200,000 people in France.
This progressive disorder destroys dopamine-producing neurons, disrupting brain communication. Primary effects include motor impairments: slowed movements, limb rigidity, resting tremors, and coordination challenges.
Beyond motor symptoms, it brings pain, fatigue, cramps, constipation, urinary urgency, excessive sweating and salivation, concentration issues, anxiety, sleep problems, loss of smell, and difficulties with swallowing and speech.
