Pseudoesthesia: Exploring the Intersection of Hallucinations and Sensations
Abstract
Pseudoesthesia, also known as false sensual experiences, is a phenomenon in which a person experiences sensations such as pain, touch, or temperature without any external stimulus. Pseudoesthesia has been linked to various neurological and psychiatric disorders, such as schizophrenia, migraine, and temporal lobe epilepsy. This article provides an overview of the current understanding of pseudoesthesia, including the causes, manifestations, and treatment of the phenomenon. Additionally, this article explores the potential overlap between pseudoesthesia and other types of hallucinations, and the implications this has for the diagnosis and treatment of conditions involving pseudoesthesia.

Introduction
Pseudoesthesia, also known as false sensual experiences, is a phenomenon in which a person experiences sensations such as pain, touch, temperature, or pressure without any external stimulus (Amiri et al., 2020). These sensations are often experienced in the absence of any real source of stimulation and can be interpreted as a hallucination. Pseudoesthesia is a relatively common phenomenon and has been linked to a variety of neurological and psychiatric disorders, such as schizophrenia, migraine, and temporal lobe epilepsy (Morrison et al., 2020). Despite its prevalence, pseudoesthesia is not well understood and the causes, manifestations, and treatment of the phenomenon remain largely unexplored.
Causes
The underlying causes of pseudoesthesia are still not well understood. However, there are several theories that attempt to explain the phenomenon. One such theory is the “overstimulation theory”, which suggests that the phenomenon is caused by an over-activity of the somatosensory cortex, which is responsible for processing sensations from the body (Gangopadhyay et al., 2019). Another theory is the “perceptual-cognitive theory”, which proposes that pseudoesthesia is caused by a misperception of existing sensory stimuli (Gangopadhyay et al., 2019). Additionally, pseudoesthesia has been linked to various neurological and psychiatric disorders, such as schizophrenia, migraine, and temporal lobe epilepsy (Morrison et al., 2020).
Manifestations
The manifestations of pseudoesthesia vary depending on the individual and the underlying cause. Common manifestations include feeling pain, touch, temperature, and pressure without any external stimulus (Amiri et al., 2020). Additionally, many individuals with pseudoesthesia experience other types of hallucinations, such as auditory or visual hallucinations, as well as other sensory distortions (Morrison et al., 2020).
Treatment
Due to the lack of understanding of pseudoesthesia, there is currently no established treatment for the phenomenon. However, some treatments have been found to be effective in reducing the symptoms of pseudoesthesia in some individuals. These treatments include cognitive-behavioral therapies, such as exposure therapy and cognitive restructuring, as well as medications such as antipsychotics and anticonvulsants (Gangopadhyay et al., 2019). Additionally, some individuals have found relief from alternative treatments, such as acupuncture, yoga, and meditation (Morrison et al., 2020).
Conclusion
Pseudoesthesia is a relatively common phenomenon that is still not well understood. The causes, manifestations, and treatment of the phenomenon remain largely unexplored, and there is no established treatment for the condition. However, various treatments have been found to be effective in reducing the symptoms of pseudoesthesia in some individuals. Additionally, there is potential overlap between pseudoesthesia and other types of hallucinations, which may have implications for the diagnosis and treatment of conditions involving pseudoesthesia.
