It’s estimated that 30% of the world’s population suffers from insomnia, making it one of the most common sleep disorders. While there are many different potential causes of insomnia, research has shown that the amygdala and hippocampus may play a role in the development and maintenance of the condition.
1. What are the amygdala and hippocampus, and what do they do in the brain
The amygdala is responsible for processing emotions, including fear and anxiety. It’s believe that people with insomnia have an overactive amygdala, which causes them to be more alert and stressed, making it difficult to fall asleep. The hippocampus is responsible for forming memories, and research has shown that people with insomnia have a reduced hippocampus volume. This may make it harder for them to forget about the stressful events of the day and relax enough to fall asleep. In a healthy person these two parts of the brain utilize bidirectional communication in order to maintain homeostasis. More often than not a negative experience or trauma can cause an imbalance in the communication causing one to experience anxiety, fear, intrusive thoughts and sleep disturbances.
2. How does the relationship between these two parts of the brain affect insomnia
The hormones released by the amygdala, such as cortisol, can interfere with the hippocampus’ ability to form new memories. This can make it difficult for people with insomnia to forget about the stressful events of the day and relax enough to fall asleep. In addition, the overactive amygdala can make people with insomnia more alert and stressed, making it difficult to fall asleep. Other hormone imbalances caused by the amygdala-hippocampus relationship can also contribute to insomnia, such as increased levels of adrenaline.
3. What implications does this have for people who suffer from insomnia
There are a few implications that this research has for people who suffer from insomnia. First, it’s important to understand that the relationship between the amygdala and hippocampus may play a role in the development and maintenance of the condition. Second, it’s possible that imbalances in hormones caused by this relationship can contribute to insomnia. Finally, this research suggests that treatments for insomnia should focus on balancing the communication between the amygdala and hippocampus.
4. Are there any treatments or methods that can help to improve the relationship between these two areas of the brain
The first step is to identify any lifestyle trigger that may be interrupting the bodies natural sleep cycle. Some common triggers include: caffeine, working night shifts, using electronic devices before bed, and stress. Once any potential triggers have been identified, there are a few methods that can help to improve the communication between the amygdala and hippocampus, and thus improve insomnia.
The most successful technique to restore the communication within the brain is to utilize dynamical neurofeedback. This is a computer-based training that uses real-time measures of EEG brain activity to provide feedback that can help improve sleep. It is a relaxing and noninvasive treatment with no side effects.
Another effective method is the use of cranial stimulation thereapy (CES). CES is a method that uses electrical stimulation to the thalmic region of the brain in order to help improve communication between the amygdala and hippocampus. The procedure takes approximately 30 minutes and is completed by wearing ear clips linked to the CES device twice a day for 6-8 weeks.
Both of these techniques have been shown to be effective in reducing the symptoms of insomnia and restoring the communication between the amygdala and hippocampus. If you suffer from insomnia, it’s important to speak with a sleep specialist too. We collaborate with a fantastic group of professionals that we can refer you to.
Other methods that can help improve the communication between the amygdala and hippocampus include: acupuncture, meditation, yoga, and aromatherapy. To find out which method is best for your unique situation, schedule a visit with us today.
5. In conclusion
The relationship between the amygdala and hippocampus is thought to play a role in the development and maintenance of insomnia. Imbalances in hormones caused by this relationship can contribute to the condition, and treatments for insomnia should focus on balancing the communication between these two areas of the brain. There are many factors that may contribute to the development of insomnia, so it’s important to speak with a specialist to determine which method is best for your unique situation.
