Neurologist Dr. David Pérez is challenging common misconceptions regarding the inheritance of neurodegenerative diseases, stating that Alzheimer’s and dementias do not follow a direct inheritance pattern. In his book Cuida tu salud cerebral
(Take Care of Your Brain Health), released on March 18, 2026, the specialist emphasizes that cognitive decline is not an unavoidable outcome of aging and is instead the result of a complex interaction between genetic and environmental factors.
Dr. Pérez, who serves as the head of neurology services at both La Luz Hospital and 12 de Octubre in Madrid, explains that while genetics play a role, familial forms of cognitive decline caused by specific genetic mutations represent only a small fraction of all cases.
The Role of Genetics and Environment
According to Dr. Pérez, the discovery of rare genetic forms of the disease has been instrumental in advancing the medical understanding of neurodegenerative conditions, particularly Alzheimer’s. However, these direct inheritance patterns are not the norm for the majority of patients.

The neurologist highlights that a significant portion of cognitive decline may be preventable. He suggests that up to 40% of cases could potentially be delayed or prevented by addressing modifiable risk factors throughout a person’s life.
Distinguishing Normal Aging from Cognitive Decline
A central theme of Dr. Pérez’s guidance is the importance of distinguishing between the natural cognitive changes associated with aging and the early warning signs of neurodegenerative disorders. He notes that certain lapses in memory, such as misplacing keys or forgetting the name of a new acquaintance, are often perfectly normal and not necessarily cause for alarm.
Despite this, he warns that We find specific indicators that should not be ignored, as they may serve as early indicators of more serious neurological problems.
Professional Background and Research
Dr. Pérez brings over 20 years of clinical experience in treating complex neurological disorders to his research. His medical training includes specialties at the 12 de Octubre Hospital in Madrid and the Neurology Department of Indiana University in the United States.
In addition to his clinical work, he holds several academic and leadership positions, including:
- Professor of neurology at the Complutense University School of Medicine.
- President of the Madrid Neurology Association.
- Director of neurology services at La Luz Hospital and 12 de Octubre.
His contributions to the field include the publication of approximately one hundred scientific articles in medical journals and contributions to more than a dozen books on neurology. His current research continues to focus on various areas related to dementia and Alzheimer’s disease.
The overarching goal of his recent work, as detailed in his March 18, 2026, publication, is to provide a guide for aging without cognitive decline by explaining the mechanisms of the brain and the influence of lifestyle and environmental factors on long-term brain health.
