When you’re in a relationship with a narcissist, your brain becomes overwhelmed by constant emotional manipulation, gaslighting, and unpredictable mood swings. Over time, this takes a serious toll on your mental health and cognitive abilities, making you feel like you’re going crazy, like your brain isn’t working properly. And that’s because it isn’t.
1. Memory Problems
One of the most common complaints from those who have experienced narcissistic abuse is memory impairment. You may struggle to recall simple things, such as appointments, conversations, or recent events. This isn’t just normal forgetfulness or aging, it’s a direct result of the intense mental and emotional stress caused by the narcissist.
The constant manipulation and gaslighting keep you in a state of fight-or-flight, flooding your brain with cortisol and other stress hormones. These hormones interfere with the hippocampus, the brain region responsible for forming, processing, storing, and retrieving memories.
Day after day, your mental energy is consumed by the narcissist’s chaos, leaving little cognitive bandwidth for everyday tasks. Even when you do remember things accurately, the narcissist may distort or invalidate your recollections, causing you to doubt yourself and lose trust in your memory. They may even use this against you, suggesting you have dementia.

2. Memory Fragmentation
Memory fragmentation occurs when memories become disjointed and no longer fit together cohesively. This is due to constant invalidation, manipulation, and gaslighting that disrupt the hippocampus’s normal functioning. Chronic stress also impairs the prefrontal cortex, which organizes and makes sense of memories.
As a result, your memories may feel out of order, or you might confuse one conversation with another. In extreme and prolonged cases of narcissistic abuse, you may struggle to distinguish between reality and the distorted narratives imposed by the narcissist.
3. Rumination and Overthinking
You may find yourself obsessively replaying past events or conversations, as if your brain is stuck in a never-ending loop. The hurtful and confusing things the narcissist said or did cycle through your mind, trapping you in the past and making it impossible to make sense of their behavior.
You might analyze every interaction, wondering what you could have done differently, while also trying to predict their next move to protect yourself from their outbursts.
This constant mental analysis consumes so much cognitive energy that there’s little left for anything else.
4. Inattention
Many people describe feeling like their brain is cluttered or foggy, with constant mental noise making it hard to concentrate. The chronic stress of narcissistic abuse impairs your ability to focus on anything other than survival. Your brain is preoccupied with decoding the narcissist’s behavior, tracking their lies, inconsistencies, and double standards, and protecting yourself from harm.
With your cognitive resources drained by these mind games, you may struggle to stay on task or concentrate. You might start reading, working, or watching TV, but quickly lose focus, your mind wandering. In severe cases, you may find it difficult to follow conversations or stay mentally engaged, leaving you feeling overloaded and mentally fried.
5. Judgment and Decision Making
Simple decisions, like what to eat or wear, can feel overwhelming. This is a direct result of the constant mental strain and emotional stress imposed by the narcissist. While it may seem manageable at first, living in a state of anxiety, fear, and self-doubt impairs basic cognitive functions.
The prefrontal cortex, responsible for decision-making, planning, and problem-solving, becomes overloaded by the ongoing chaos. This makes it difficult to think, assess situations rationally, or weigh options effectively.
The longer you remain in this abusive environment, the harder it becomes to make even small decisions. You might feel paralyzed by choices or unable to act, which can trap you in an abusive relationship. Even if you intellectually recognize that you deserve better, the emotional stress and fear can make it nearly impossible to trust or act on your judgment.
6. Cognitive Dissonance
Cognitive dissonance occurs when you hold two conflicting beliefs or attitudes, creating psychological tension and discomfort. In narcissistic abuse, you may struggle to reconcile the narcissist’s occasional sweetness, charm, or affection with their cruelty, neglect, or hateful behavior. This leads to confusion as your brain tries to make sense of these contradictions.
To reduce this internal conflict, you might minimize or rationalize the narcissist’s behavior, telling yourself they didn’t mean to hurt you, were stressed, or will change, despite overwhelming evidence to the contrary. This self-deception serves as a coping mechanism to avoid facing the harsh reality.
7. Cognitive Fatigue
Cognitive fatigue is the mental exhaustion caused by the constant effort required to navigate the narcissist’s chaos, confusion, and drama. You’re always on edge, trying to make sense of their manipulations, avoid their outbursts, and decipher their behavior. This relentless mental abuse doesn’t ease with time or rest, leaving you drained.
Over time, this exhaustion affects not only your mental capabilities but also your emotional and physical well-being, often leading to burnout. It’s like driving a car with a leaking fuel tank; no matter how much you try to refuel, you keep running out of gas.
