Another factor driving market growth is the increasing research and development activities in the field of DEE treatment. The development of novel therapies, such as gene therapies and neurostimulation devices, is expected to significantly improve the treatment options for DEE in the coming years. Additionally, the increasing use of cannabidiol (CBD) for the treatment of DEE is expected to contribute to the growth of the market.
Furthermore, the favorable regulatory environment for the development and approval of rare disease therapies is also expected to drive market growth. Regulatory agencies, such as the USA FDA, have implemented expedited pathways for the development and approval of rare disease treatments, which could benefit the DEE treatment market.
In conclusion, the DEE treatment market is expected to grow in the coming years due to the increasing awareness and diagnosis of the condition, the development of novel therapies, and the favorable regulatory environment. However, the market still faces several challenges that need to be addressed to ensure the availability and affordability of effective treatments for individuals with DEE.
Expensive Cost of Treatment to restrict Market Growth
DEE is a rare condition, which means that the patient population is small. This can make it challenging for companies to recoup their investment in the development of treatments for DEE.
The development of treatments for rare diseases is typically expensive due to the limited patient population, which can increase the cost per patient. Additionally, regulatory requirements for rare disease treatments can be more stringent, which can also increase the cost of development.
