The findings were published Tuesday in the journal Parkinson\u2019s Disease.<\/p>\n<p data-start=\"734\" data-end=\"1005\">Parkinson\u2019s disease is a neurological disorder that primarily affects body movement and is caused by the damage or loss of specific nerve cells in the brain responsible for producing dopamine \u2014 a neurotransmitter that plays a key role in regulating movement and balance.<\/p>\n<p data-start=\"1007\" data-end=\"1357\">Key symptoms include tremors in the limbs, slowed movement, muscle stiffness, difficulty with balance and walking, as well as psychological changes such as depression and memory issues. Parkinson\u2019s is a chronic condition with no known cure, but medications and surgical interventions can help alleviate symptoms and improve patients\u2019 quality of life.<\/p>\n<figure id=\"attachment_14105\" aria-describedby=\"caption-attachment-14105\" style=\"width: 1024px\" class=\"wp-caption alignleft\"><img decoding=\"async\" class=\"wp-image-14105 size-large\" src=\"https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire0000000-1024x614.jpg\" alt=\"Parkinson\u2019s disease detection\" width=\"1024\" height=\"614\" srcset=\"https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire0000000-1024x614.jpg 1024w, https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire0000000-300x180.jpg 300w, https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire0000000-768x461.jpg 768w, https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire0000000.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption id=\"caption-attachment-14105\" class=\"wp-caption-text\">Parkinson\u2019s is a chronic condition with no known cure, but medications and surgical interventions can help alleviate symptoms and<\/figcaption><\/figure>\n<p data-start=\"1359\" data-end=\"1616\">In the study, the research team trained two dogs \u2014 a Golden Retriever and a Labrador \u2014 to differentiate between skin swabs taken from the sebum (an oily substance secreted by the skin) of individuals with Parkinson\u2019s and those of healthy people.<\/p>\n<p data-start=\"1618\" data-end=\"1959\">Using a double-blind trial method to ensure scientific accuracy, the dogs demonstrated a sensitivity of 80% (i.e., correctly identifying patients who had Parkinson\u2019s) and a specificity of 98% (i.e., accurately ruling out individuals who did not have the disease), even when the samples came from people with other medical conditions.<\/p>\n<p data-start=\"1961\" data-end=\"2259\">According to the researchers, one of the most remarkable findings was that the dogs could identify Parkinson\u2019s even in samples from people with unrelated health issues \u2014 suggesting the existence of a unique scent \u201csignature\u201d for the disease that could potentially be used in clinical diagnosis.<\/p>\n<p data-start=\"2261\" data-end=\"2667\">Currently, there is no definitive early diagnostic test for Parkinson\u2019s. Diagnoses typically rely on observing symptoms that may not appear until 10 to 20 years after the disease has already begun to affect the body. Using trained dogs and skin swabs could allow for early detection, giving patients a better chance to begin treatments that may slow disease progression and reduce its severity.<\/p>\n<figure id=\"attachment_14104\" aria-describedby=\"caption-attachment-14104\" style=\"width: 1024px\" class=\"wp-caption alignleft\"><img decoding=\"async\" class=\"wp-image-14104 size-large\" src=\"https:\/\/www.watanserb.com\/en\/wp-content\/uploads\/2025\/03\/ceasefire000000-1024x601.jpg\" alt=\"Currently, there is no definitive early diagnostic test for Parkinson\u2019s.

This opens up the possibility of developing electronic devices that mimic a dog\u2019s sense of smell \u2014 known as an \u201celectronic nose.\u201d<\/p>\n<p data-start=\"2979\" data-end=\"3254\">They also noted that using dogs or skin swabs for diagnosis is less costly and less invasive than traditional methods like brain scans or complex neurological exams. This could make the technique suitable for wider use, particularly during preliminary screenings.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Watan-A recent British study has found that trained dogs are capable of detecting Parkinson\u2019s disease by smelling skin, with an accuracy rate of up to 98% \u2014 a promising step that could help diagnose the condition earlier.
