The global central nervous system therapeutics market size was estimated at USD 138.59 billion in 2025 and is projected to reach USD 273.32 billion by 2033, growing at a CAGR of 9.1% from 2026 to 2033. The central nervous system (CNS) therapeutics market is experiencing robust growth, driven largely by the rising prevalence of neurological and psychiatric disorders.
As the global population ages, coupled with the impact of modern lifestyle choices, the incidence of diseases such as Alzheimer's disease, Parkinson's disease, epilepsy, multiple sclerosis, and mental health disorders is steadily increasing. This expanding disease burden is catalyzing significant demand for new and improved therapeutic options. As the need for effective treatments grows, pharmaceutical and biotechnology companies are ramping up investments in CNS drug development, and governments are offering increased support for research initiatives.
The global aging population is one of the most significant drivers of rising disease prevalence in the CNS therapeutics market. According to the WHO, the ratio of the world's population aged 60 years and older is anticipated to double by 2050, from approximately 12% in 2015 to 22%. Neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and other dementias, are primarily age-related and are becoming more prevalent as life expectancy increases. Alzheimer's disease, which currently affects more than 55 million people worldwide, is predicted to nearly triple by 2050. Similarly, Parkinson's disease affects an estimated 10 million people globally, and this number is expected to rise due to the aging population. As a result, there is a growing demand for effective treatments, particularly those that can delay the progression of these debilitating diseases or modify their course. Despite the increasing prevalence, current treatment options for neurodegenerative diseases remain limited, with no cure available. This has led to increased investment in novel therapies, including disease-modifying treatments and targeted drug delivery systems aimed at overcoming the blood-brain barrier.
Beyond aging, modern lifestyle factors such as stress, poor diet, sedentary behavior, and environmental pollution are contributing to the rising prevalence of both neurological and psychiatric disorders. These factors have been linked to an increase in stroke, migraine, and mental health conditions such as anxiety, depression, schizophrenia, and bipolar disorder. Mental health issues are becoming a leading cause of disability worldwide. The WHO estimates that over 300 million people suffer from depression globally, and the number is steadily increasing. This growing prevalence of psychiatric disorders is pushing for new therapeutic options that address the root causes of conditions such as depression and schizophrenia. The need for treatments that are more effective, have fewer side effects, and offer better long-term outcomes has never been greater.
The rising prevalence of Alzheimer's disease is expected to boost market growth. Alzheimer's disease is a global epidemic, and its diagnosis rate is about 25% globally. The diagnosis rate of Alzheimer's disease is high in developed countries. In North America and some European countries, the diagnosis rate of Alzheimer's disease is nearly 50%, whereas, in developing countries such as India & China, it varies from 10%-15% of total Alzheimer's cases. In addition, according to NCBI, in 2021, about 6.2 million people aged 65 and above living in America were suffering from Alzheimer's disease, which is estimated to increase to around 13.8 million by 2060.
Furthermore, an increase in the incidence and cost burden of dementia associated with Alzheimer's disease worldwide is expected to boost market growth. According to the Alzheimer's Society, there are around 900,000 people living with dementia in the UK, and it is projected to rise to 1.6 million by 2040 and the incidence of dementia will be 209,600 in the same year.
Alzheimer's disease is becoming the most common cause of death in neurodegenerative diseases and a common cause of physical disability. The disease is most common in females as compared to males. For instance, two in three people with the disease are women. The age distribution for Alzheimer's disease across the globe includes 4% aged 65 or younger, 13% aged between 65 and 74, 44% aged 75 to 84, and 38% aged 85 or older.
