Dr. Katzman's research primarily studies mental health issues, particularly during and after pregnancy, as well as among student-athletes and patients with conditions like PTSD and liver disease. He explores how electronic systems can help monitor and improve treatment for perinatal depression and anxiety, emphasizing the need for better mental health resources in collegiate sports. Additionally, he investigates the effects of brain stimulation on mood and anxiety in animal models, the differences in fear responses between genders in PTSD, and how nutritional factors like breakfast can enhance cognitive performance in patients with liver disease.
Key findings
In a trial for perinatal depression and anxiety, 76% of 42 participants completed follow-up surveys, indicating the feasibility of electronic monitoring.
Among 21 interviewed NCAA Division III athletes, stress and identity loss were identified as major reasons for discontinuing their sports, highlighting the importance of mental health support.
Deep brain stimulation in a mouse model showed reduced anxiety-like behavior, with significant changes in serotonin levels indicating complex brain interactions.
In a PTSD model, female rats displayed different fear responses compared to males, suggesting a need for gender-specific treatments in PTSD.
Breakfast improved cognitive function in cirrhotic patients with cognitive impairment, leading to better attention and executive skills despite higher ammonia levels.

Burnout, Identity Loss and Institutional Gaps: A Qualitative Examination of Sport Discontinuation Among NCAA Division III Athletes.
2025
Sports (Basel, Switzerland)
Stavitz J, Porcelli R, Block-Lerner J, Marks DR, Katzman H
Plain English This study looked at why some NCAA Division III student-athletes stop playing their sport, focusing on mental health issues. Researchers talked to 21 former athletes and found that stress, burnout, and a loss of identity were major reasons for their decisions, alongside a lack of support from their schools. The study shows that improving mental health resources and support for these athletes is crucial for their well-being and for keeping them in sports.
Who this helps: This benefits student-athletes, coaches, and school administrators.

Askari N, Gupta R, Hussain-Shamsy N, Barker LC, Champagne T +10 more
Plain English This study looked at a new way to provide care for people experiencing depression and anxiety during and after pregnancy, using a system that tracks their symptoms electronically. Out of 42 participants, 76% completed follow-up surveys, and most of the time (87.5%), symptom scales were used during visits, although only about 69% of these included discussions between patients and their healthcare providers. While the results showed slight improvements in depression and anxiety scores, they were not significant; however, the study confirmed that this method of care could be tested on a larger scale in the future.
Who this helps: This approach benefits patients facing perinatal depression and anxiety by potentially improving how their symptoms are monitored and treated.
Sex differences in long-term fear and anxiety-like responses in a preclinical model of PTSD.

Journal of psychiatric research
Emtyazi D, Rabelo TK, Katzman H, Campos AC, Diwan M +6 more
Plain English This study looked at how male and female rats respond to fear, focusing on differences in long-term fear and anxiety-like behaviors, which could help us understand posttraumatic stress disorder (PTSD), especially in women. Researchers found that female rats showed less fear during a recall task and were quicker to eat in a stressful situation compared to males, but overall fear and anxiety responses were similar across sexes. This matters because it helps us identify potential differences in how PTSD affects men and women, which could lead to better treatment approaches.
Who this helps: This research benefits patients with PTSD, particularly women, and their healthcare providers.
Serotonin 5-HTreceptors mediate the antidepressant- and anxiolytic-like effects of ventromedial prefrontal cortex deep brain stimulation in a mouse model of social defeat.
2022
Psychopharmacology
Silk E, Diwan M, Rabelo T, Katzman H, Campos ACP +4 more
Plain English This study looked at how deep brain stimulation (DBS) in a specific brain region called the ventromedial prefrontal cortex (vmPFC) affects mood and anxiety in mice that have faced chronic social stress. The researchers found that when these mice were stimulated, they showed less hesitation to eat in a stressful environment and were less likely to be immobile in a forced swimming test, indicating reduced anxiety and depression. While serotonin levels increased in certain brain areas after stimulation, it also decreased in others, suggesting a complex interaction; specifically, the positive effects were partly tied to serotonin receptors.
Who this helps: This research may benefit patients with depression and anxiety disorders seeking new treatment options.
Breakfast improves cognitive function in cirrhotic patients with cognitive impairment.
2010
The American journal of clinical nutrition
Vaisman N, Katzman H, Carmiel-Haggai M, Lusthaus M, Niv E
Plain English This study examined how having breakfast affects the thinking abilities of patients with liver disease who have mild cognitive problems. Researchers found that, after eating breakfast, these patients showed improved attention and executive functions, even though their ammonia levels, which can be harmful, increased. This is important because it suggests that having a balanced meal in the morning may help improve mental performance in these patients, potentially reducing the impact of their liver condition on daily life.
Who this helps: This helps patients with liver disease and their healthcare providers.
Community pharmacist interventions in a capitated pharmacy benefit contract.
1998
American journal of health-system pharmacy : AJHP : official journal of the American Society of Health-System Pharmacists
Knapp KK, Katzman H, Hambright JS, Albrant DH
Plain English This study looked at how community pharmacists address problems with prescriptions for patients enrolled in a managed care plan in California. Researchers analyzed 595 interventions carried out by 31 pharmacies, finding that 50% of the issues were related to drug selection, and the most common action taken was contacting the prescribing doctor, which occurred 56.1% of the time. Overall, pharmacists intervened in only 0.7% of prescriptions, with some pharmacies doing this as often as 4.1%, and interventions that led to prescription changes saved an average of 65.8% in costs.
Who this helps: This helps patients who rely on prescribed medications and their healthcare providers.
Plain English This study looked at how diamond powder can be bonded together using cobalt to create strong, dense materials. Researchers found that by using 20% cobalt and diamond particles sized between 1 and 5 micrometers, they achieved a maximum hardness of 3000 kilograms per square millimeter. This is significant because these tough materials can have important applications in cutting tools and industrial machinery.
Who this helps: This benefits manufacturers and industries that rely on durable cutting tools.
