Dr. Robert Kohn

A physician with decades of experience as a geriatric psychiatrist, Dr. Robert Kohn is a temporary advisor for the Pan American Health Organization/World Health Organization. Dr. Robert Kohn also serves as a professor of psychiatry in a local medical school in Providence, Rhode Island. In his solo practice clinic in Providence, Robert Kohn, MD, treats older adults with intellectual and developmental disorders, such as Alzheimer’s disease and other forms of dementia.

A team of scientists has found that sleep deprivation may cause impairment in the brain, and lack of sleep over long periods may be linked to an increased risk of Alzheimer’s disease. The study was published in the American Chemical Society’s Journal of Proteome Research.

The researchers used mice to discover that sleep deprivation can cause neurologic damage to the hippocampus, the part of the brain primarily involved in learning and memory. During the study, the mice were evaluated based on how well they navigated through a maze and how they recognized new objects in the maze after being deprived of sleep for two days. Then, proteins were extracted from the mice’s hippocampi and noted how the abundance of such proteins had changed. They also compared the mice’s performance with other animals not involved in the study.

The researchers found that the pleiotrophin (PTN) of the mice that lacked sleep declined, which may eventually lead to the death of the hippocampus. PTN is a protein-coding gene associated with growth factors. Compared with human genetics studies, PTN is implicated in neurodegenerative diseases such as Alzheimer’s.

Experienced geriatric psychiatrist Dr. Robert Kohn is a temporary advisor to Pan American Health Organization/World Health Organization (PAHO/WHO). A recognized presence in geriatric psychiatry, Dr. Kohn has written or co-authored more than 200 articles, research papers, abstracts, book chapters, and presentations. Robert Kohn, MD, maintains a solo practice clinic in Providence, Rhode Island, where he sees older adults with intellectual and developmental disorders, including dementia.

Early prediction of dementia is now possible. Researchers from the University of Florida College of Medicine found a new tool that may predict the likelihood of a person getting dementia.

The team analyzed the data of about 13,000 participants. The researchers used the rating given by interviewers about each participant’s cognitive health over 15 years. The researchers analyzed the data of participants who had their first interview in 2006 and were interviewed again between 2008 and 2020.

It is to be noted that the participants did not have any cognitive impairment at baseline, were at least 50 years old, and had participated in the University of Michigan Health and Retirement Study (HRS). The researchers used the data from the HRS as the initial point of reckoning and the succeeding interviews as points of comparison.

During the interview, the participants were rated on how much difficulty they had remembering things already asked them before. On a scale of 1 to 5, the participants were rated as “having no difficulty at all” (1) and “cannot remember anything at all (5).

The researchers said that every point of increase in poor memory is associated with a 40 percent higher risk of getting dementia over the research period. The association is similar regardless of age, gender, education, ethnicity, or race.

An experienced psychiatrist with a clinical focus on geriatric psychiatry, Dr. Robert Kohn earned his MD and completed his psychiatry residency at the University of Illinois in Chicago and Brown University, respectively. Dr. Robert Kohn has also conducted research on the rates and risk factors among adults and children for various conditions. His research in geriatric psychiatry has examined the rates of mental illness and its risk factors, including neuropsychiatric risk factors, obsessive-compulsive disorder, and post-traumatic stress disorder (PTSD).

Exposure to stressful events can result in post-traumatic stress disorder (PTSD), a mental disorder characterized by reliving traumatic events through flashbacks and nightmares, and feelings of guilt, irritability, and isolation. PTSD is typically associated with traumatic stressors that are extremely severe and challenging to cope with, such as rape and combat. These experiences typically overwhelm an individual’s stress response system.

The likelihood of developing PTSD due to subsequent exposure to trauma is high when someone has already experienced a traumatic event. Vulnerability is particularly high when the pathological mechanisms of PTSD manifest before the later stressor. If an individual has experienced a traumatic event but has not developed signs or symptoms of PTSD, this demonstrates that they have successfully managed the previous experience from a psychological perspective and are less likely to develop PTSD if they undergo a similar event later. Most people achieve this by seeking mental health support and modifying their daily routines and lifestyle.

A geriatric psychiatrist, educator, and researcher, Robert Kohn, MD, treats older patients with intellectual and developmental disorders. A recognized presence in the medical profession, Dr. Kohn serves as a temporary advisor to Pan American Health Organization/World Health Organization (PAHO/WHO). Dr. Robert Kohn maintains membership in the American Psychiatric Association (APA), where he is also a distinguished Fellow.

APA is a premier psychiatric association that promotes equitable access to the best available healthcare for people with mental disorders and substance disorders. APA’s advocacy includes working with Congress on the passage of significant bills that affect the practice of psychiatry.

APA lauded the passage of the Consolidated Appropriations Act of 2023, which provides for a $1.7 trillion omnibus package, including investments in the psychiatric workforce, enforcement of mental health parity, and collaborative care. The bill was signed by President Joe Biden on December 29, 2022. APA has advocated heavily for the passage of this bill.

Under the bill, 200 new graduate medical education residency slots will be created. Half of these positions are designated for psychiatry and its subspecialties. The bill will also enforce the Mental Health Parity and Addiction Equity Act of 2008 by granting funds to state insurers. The bill also provides funds for grants and technical assistance for the enforcement of the Collaborative Care Model in primary care settings, thereby increasing early intervention for treatment or prevention of mental and substance use disorders.

Dr. Robert Kohn is a health care provider based in Providence, Rhode Island, with nearly forty years of experience and an MD. He is a consultant to the World Health Organization and the Pan-American Health Organization and a distinguished fellow of the American Psychiatric Association. With a primary specialty in psychiatry, Dr. Robert Kohn focused his academic work on geriatric psychiatry, global mental health, psychiatric epidemiology, and cultural psychiatry.

Cultural psychiatry is concerned with the interplay between cultural diversity and mental health services. There are various ways in which culture shapes and influences mental health.

Cultural or ethnic background influences the aid individuals receive from family and friends. It also impacts their access to therapy when they deal with mental health issues. Different ethnicities recognize stigmas shaping how their members embrace mental health services. In the United States, minorities also have limited access to health care providers.

Culture equally affects mental health access in the area of reporting. A health care provider may not be able to render the requisite care to minorities due to a lack of records of members who previously experienced the condition in question. This invariably affects the therapy sessions that follow.
