Falling in love is one of the most intense and transformative feelings a human being can experience. It is often associated with a state of enchantment, where the perception of the world and relationships changes profoundly. Often described as a temporary "madness", falling in love, from the perspective of neuroscience, can in fact be understood as a type of temporary dementia — a condition that directly affects brain function and perception of reality.
Passion from a Neuroscientific Perspective
Neuroscientists have been studying the impact of emotions on the human brain, and when it comes to passion, the studies reveal an intriguing picture. Passion is associated with intense activation of brain areas linked to the reward system, such as the nucleus accumbens , the prefrontal cortex and the amygdala . These centers are involved in pleasure, decision-making and emotional processing.
When a person falls in love, the brain releases a series of chemicals, such as dopamine , norepinephrine and oxytocin , which cause euphoria, excitement and the desire for closeness with the object of affection. The euphoria generated by these neurotransmitters can be so overwhelming that many individuals feel "out of control" while in love.
Temporary Dementia
The term "temporary dementia" is used figuratively to describe the effects of infatuation on the mind. While the word "dementia" refers to a permanent degenerative condition of the brain, temporary dementia in this context refers to a temporary alteration in cognition, decision-making, and perception of reality. During infatuation, a person's judgment can be seriously impaired, and this is what makes infatuation seem like a type of "madness."
Change in Perception
One of the main manifestations of this state is the distortion of perception. When someone is in love, they often ignore their partner's flaws or negative aspects, overestimating their qualities and creating an idealized image of the other person. Infatuation can lead a person to behave irrationally, make impulsive decisions and act in ways they would not do in a more balanced emotional state.
Focus on the Object of Affection
Another effect of falling in love on the brain is the exclusive focus on the object of affection. Romantic love activates areas of the brain associated with focus and attention. This can lead to a state of extreme concentration on the partner, in which the rest of the world seems to lose importance. The brain in love becomes obsessed with the details of the relationship, which can result in compulsive behaviors, such as the desire for constant communication or the need for approval from the partner.
Loss of Control and Rationality
During a state of infatuation, emotional impulses often override rationality. This can be seen in rash decisions, such as entering into relationships without considering the long-term consequences, or ignoring warning signs in a relationship, for example. This behavior can be compared to a form of temporary “madness,” where reason is overshadowed by emotional intensity.
The Reward Cycle
On a neurobiological level, falling in love can be seen as a reward cycle. Each interaction with a loved one generates a “hit” of dopamine, creating a feeling of pleasure and reinforcing the desire to be with that person. This reward cycle can create a state of emotional dependence, where the brain constantly seeks more positive stimuli from the partner, which further increases the intensity of falling in love.
Passion and Its Long-Term Effects
Although infatuation is an overwhelming experience, it tends to be short-lived. The human brain eventually adapts to the increased levels of dopamine and other neurotransmitters, and the euphoric state subsides. What remains of the initial infatuation may develop into a deeper, more lasting love, but the intensity of the infatuation fades. The "temporary dementia" subsides, giving way to a more rational and balanced way of relating.
From a neuroscientific perspective, falling in love can be considered a state of “temporary dementia” due to the intense effects it has on the mind and behavior. During this period, the brain is overwhelmed by chemicals that cause changes in judgment, perception, and decision-making. Although falling in love can be overwhelming, it is short-lived, and over time, neurobiological changes stabilize, allowing relationships to mature or dissipate.
Many books on neuroscience, psychology, and neurobiology discuss the effects of passion on the brain and how it can be compared to a form of “madness” or temporary distortion of perception and cognition. Below, I list some works that address passion, love, and the neurobiological effects of these intense feelings:
"The Brain in Love" - Dr. Helen Fisher
"The Biology of Love" - Dr. Judith D. Sherven and Dr. James S. Gray
"The Power of Love" - Dr. John Cacioppo and Stephanie Cacioppo
Although the concept of "temporary insanity" is not a technical term used in scientific literature on passion, many of these books explore how passion affects the brain, leading to intense behavioral and emotional changes that can be perceived as a form of "temporary madness." The idea that passion changes perceptions of reality and influences behavior in irrational ways is widely discussed in neuroscience, especially in studies of the intense emotions involved in romantic love.
