Learn the symptoms of low dopamine sensitivity. If you have low dopamine sensitivity, you'll have little joy for life. You'll be low on energy and motivation, and will often rely on caffeine, sugar, or other stimulants to get through the day. Low dopamine levels or sensitivity can also manifest as certain psychiatric disorders including depression, attention deficit disorder (ADD), bipolar disorder, and addictions of all kinds. Here's a list of the most common dopamine desensitization symptoms:
[4]
- Lack of motivation
- Fatigue
- Apathy
- Procrastination
- Inability to feel pleasure
- Low libido
- Inability to connect with others
- Sleep problems
- Mood swings
- Hopelessness
- Memory loss
- Inability to concentrate
- Inability to complete tasks
- Engaging in self-destructive behaviors, especially addictions
Desensitization is caused by a number of factors, including:
[3]
- 1: Decline in dopamine (D2) receptors. Fewer D2 receptors mean less sensitivity to available dopamine, which leaves a person less sensitive to the pleasure normally found in experiences.
- 2: Decline in baseline (tonic) dopamine levels. Lower dopamine levels leave a person "hungry" for dopamine-raising activities/substances of all kinds.
- 3: Blunted dopamine in response to normal rewards. Dopamine normally rises in response to rewarding activities. Once your addiction is the most reliable source of dopamine, cravings arise urging you to use porn.
- 4: Decline in CRF-1 receptors, which function to raise dopamine levels in the striatum (part of the brain).
- 5: Loss of reward circuit grey matter, which means a loss of dendrites. This translates into fewer nerve connections or synapses. A 2014 study on porn users correlated less grey matter with more porn use.
- 6: Decline in opioids or opioid receptors.
- Both #2 and #3 may involve increased dynorphin which inhibits dopamine, and weakening of certain pathways (glutamate) conveying messages to the reward circuitry. In other words, desensitization is rather complex, and an awful lot is left to learn.
