Dementia is a health crisis sweeping the globe. Experts estimate that roughly 50 million people worldwide are currently living with this condition. That enormous figure is expected to nearly double to 80 million by 2030 and potentially surpass 150 million by 2050. Alarmingly, a new dementia diagnosis happens every three seconds.

Dementia, a condition primarily recognized for its devastating impact on cognitive function, currently affects over 55 million people globally, according to the World Health Organization

Depression is a pervasive and debilitating mental health disorder impacting millions globally. Effective treatments, such as Person-Centered Experiential Therapy (PCET) and Cognitive Behavioral Therapy (CBT), aim to alleviate symptoms and improve the overall quality of life for individuals experiencing moderate to severe depression. The trajectory of recovery in these therapies can vary significantly among patients, and understanding the factors influencing these differences is crucial for enhancing therapeutic outcomes. A pivotal area of investigation is the differential effect of early treatment response on final outcomes within PCET and CBT frameworks. This essay will analyze a study by Ardern et al. (2025), which explores how early symptom changes impact final treatment outcomes and whether these effects differ between PCET and CBT. This analysis will delve into the methodological approach, key findings, and clinical implications of this research, illuminating the nuances of early therapeutic responses in depression treatment.
