Research suggests that caffeine may help to relieve depressive symptoms or help to protect against depression. A 2016 meta-analysis accounting for a total of 346,913 individuals and 8,146 cases of depression suggested that coffee consumption may have a protective effect.
“Caffeine triggers our heart rate and studies have conclusively shown that caffeine consumption raises blood pressure,” says registered nutritionist Elizabeth Yontz Moye. When your nervous system is targeted by too much caffeine it can cause you to not only have the jitters but mood swings and irritability.
Caffeine
Caffeine is an underappreciated bipolar trigger and can also impair sleep, he says, which can be particularly problematic because sleep deprivation is a notorious trigger for bipolar mood swings and mania.
Caffeine raises dopamine levels in the brain, which can cause increased anxiety, restlessness, and thus induce mania or hypomania (which can then bring on a loss of appetite when you have bipolar disorder).
Many studies have shown that coffee can help to fight against depression and also improve general cognitive functions such as memory, vigilance, and your overall mood. This is due to release of dopamine, a neurotransmitter that sends signals to the brain to help us feel happiness.
Coffee contains caffeine, which is a stimulant that can boost mood and energy levels. The caffeine in coffee works by increasing the levels of certain chemicals in the brain, such as dopamine and norepinephrine, which can lead to feelings of happiness and euphoria.
Caffeine interacts with a molecule in the body called adenosine , which assists with communication between brain cells and acts as a nervous system depressant. Adenosine levels increase throughout the day and help promote feelings of drowsiness.
Most research on the effects of caffeine on people with bipolar disorder indicates that the stimulant may trigger manic episodes. Caffeine acts as a mood elevator. Some experts have suggested that caffeine may, as a result, trigger the disorder's manic episodes, which some may refer to as high periods.
Caffeine may help depression
Low levels of dopamine can make you feel tired, moody and unmotivated, among other symptoms, she said. But “having more dopamine helps patients with depression by improving their mood.”
A stressful circumstance or situation often triggers the symptoms of bipolar disorder. Examples of stressful triggers include: the breakdown of a relationship. physical, sexual or emotional abuse.
psychological treatment – such as talking therapies, which help you deal with depression and provide advice on how to improve relationships. lifestyle advice – such as doing regular exercise, planning activities you enjoy that give you a sense of achievement, and advice on improving your diet and getting more sleep.
Caffeine has been found to induce manic symptoms and trigger the onset of BD in people with no history of psychiatric disorders at baseline.
Caffeine has also been shown to increase serotonin levels in the limbic system, a relatively primitive part of our brain involved in regulating basic functions such as hormonal secretions, emotional responses, mood regulation and pain/pleasure sensations.
It was previously reported that caffeine has the capability to reduce brain serotonin synthesis by inhibiting tryptophan hydroxylase, the rate-limiting enzyme for central serotonin biosynthesis (Lim et al., 2001), and/or to reduce brain serotonin/dopamine ratio by blocking adenosine α1 and α2 receptors within the CNS.
Studies reviewed in the meta-analysis show coffee's anti-inflammatory properties are associated with decreased depression. Caffeine blocks mood-depressing chemicals in the brain. Caffeine blocks receptors in the brain from binding with a chemical (adenosine) that causes fatigue and depressed mood.
Caffeine may temporarily help some people with depression improve their mood. However, it may also make symptoms worse. Consuming 400 milligrams of caffeine is generally considered safe for most people, but this includes total daily caffeine intake from food, beverages, and supplements.
Caffeine reliably increases emotional arousal, but it is unclear whether and how it influences other dimensions of emotion such as emotional valence.
But, drinking coffee can make anxiety symptoms worse. Research shows that in people with panic disorder, caffeine consumption raises the risk of having a panic attack and increases levels of anxiety. People with anxiety should consider avoiding or limiting coffee and other caffeinated drinks.
Bipolar disorder can cause your mood to swing from an extreme high to an extreme low. Manic symptoms can include increased energy, excitement, impulsive behaviour, and agitation. Depressive symptoms can include lack of energy, feeling worthless, low self-esteem and suicidal thoughts.
Bipolar disorder is primarily a mood disorder. ADHD affects attention and behavior; it causes symptoms of inattention, hyperactivity, and impulsivity. While ADHD is chronic or ongoing, bipolar disorder is usually episodic, with periods of normal mood interspersed with depression, mania, or hypomania.
Although the results indicate that people with more ADHD symptoms do not consume more caffeine in any form, but they are probably more sensitive for the reinforcing effects of caffeine, which lead to more CUD symptoms. Therefore, caffeine does not seem to be a compound for successful self-medication.
FAQs about caffeine and ADHD
Caffeine can have a calming effect on some people with ADHD. A growing number of ADHDers have reported that caffeine has a paradoxical effect on them, making them feel calmer and sleepier after their afternoon tea.
Stimulants are believed to work by increasing dopamine levels in the brain. Dopamine is a neurotransmitter associated with motivation, pleasure, attention, and movement. For many people with ADHD, stimulant medications boost concentration and focus while reducing hyperactive and impulsive behaviors.
