Dr. Abhishek Shukla, MD, FRCP (Geriatrician), in conversation with Dr. Nirupama Jaiswal, MD (Psychiatry), discussed an important and clinically relevant topic: What is tactile hallucination? This condition is commonly misunderstood by patients and caregivers, especially in elderly individuals.
A tactile hallucination is defined as a false perception of touch, movement, or sensation on the skin or inside the body without any real external stimulus. Patients may complain of feeling worms moving under the skin, insects crawling over the body, unexplained pressure, tingling, burning, or being touched when no one is present. These sensations feel very real to the person experiencing them and can cause severe distress, anxiety, and sleep disturbance.
Dr. Shukla emphasized that before labeling these symptoms as psychiatric, medical causes must be ruled out first. Conditions such as peripheral neuropathy, vitamin deficiencies (especially Vitamin B12 and Vitamin D), diabetes, electrolyte imbalance, and age-related nerve damage can produce similar abnormal sensations. Therefore, detailed clinical examination and basic investigations are essential in the initial evaluation.
Dr. Jaiswal added that substance use is another important cause. In particular, co***ne addiction can lead to tactile hallucinations, classically described as the sensation of insects crawling under the skin, also known as “co***ne bugs.” In such cases, the hallucinations are drug-induced and require urgent medical and psychiatric intervention.
Once physical causes are excluded, consultation with a psychiatrist is crucial. Early diagnosis and appropriate treatment with medications can significantly reduce symptoms and improve quality of life. Both doctors stressed that tactile hallucinations should never be ignored, and prompt medical attention is essential for safe and effective management.
