Need some clarification, please

For the diagnosis:
Extrapyramidal syndrome

and the diagnosis:
Wilson disease

Wilson disease

Wilson disease—clinically known as hepatolenticular degeneration—is basically a genetic disorder where copper starts piling up in your tissues. Normally, your body only carries trace amounts of copper, but when this happens, the buildup triggers a mess of liver, neurological, and psychiatric issues.

The neurological side involves those extrapyramidal symptoms—basically issues with motor control. We're talking about being unable to move a limb voluntarily, losing control over movement once it starts, involuntary facial or neck grimacing, muscle rigidity, or tremors in the hands.

Psychiatric symptoms can range from depression and anxiety to full-blown psychosis—where reality gets distorted.

On the liver front, you’re looking at chronic fatigue, persistent inflammation, and an enlarged liver or spleen, which can escalate into much more serious complications.

Who's actually getting diagnosed with this? Usually someone younger. To be certain, doctors look for the "gold standard"—a liver biopsy—though they also rely on clinical symptoms, blood tests, ceruloplasmin levels, and checking copper concentrations in blood and urine. There's also a telltale sign called a Kayser-Fleischer ring—a brownish-red ring visible around the iris of the eye. Treatment usually involves penicillamine, though a liver transplant is the ultimate fix.

The patient is young; here are the liver biopsy results. I'm looking for an explanation:
Liver biopsy histopathological findings:
A 13mm liver parenchyma biopsy strip was analyzed. The lobular structure remains intact. Following histochemical staining, depending on the section, there are 6-7 narrow, compressed portal spaces where rare lymphocytes are focally present, while the limiting lamina remains preserved, etc.
Conclusion: Histochemical staining of the analyzed sample shows no deposits of bacteria or iron. The described morphological changes in the sample are non-specific and do not indicate an active necroinflammatory process; therefore, this finding must be interpreted within the context of the complete clinical picture.

What does this conclusion actually mean? Is this result positive for the patient or not?

The results aren't positive—meaning the liver biopsy doesn't confirm the clinical presentation (the actual symptoms).

In a proper liver biopsy report, you'd expect to see the copper content in the dried liver tissue specimen—it should be sitting at about 250 micrograms of copper per gram of tissue. I don't see that specific data point in this description, but even if it were there, it still wouldn't clinch the diagnosis.

To actually confirm the diagnosis, you’d need a positive Kayser-Fleischer ring in the iris, low ceruloplasmin levels (l), plus neurological symptoms.

Other ways to back up the diagnosis (though they aren't specific to Wilson disease!) include checking copper levels in the blood serum and performing a 24-hour urine collection to measure copper concentration.

For a solid confirmation, the 24-hour urine copper concentration needs to be over 100 micrograms/24h (1.6 μmol/24h)—anything above 40 micrograms/24h (0.6 micromoles/24h) is just suspicious.

I’ve been reading up on it, and from what I can gather, Wilson's disease presents itself in two distinct ways.
There seems to be one version that targets the liver and then there's a neurological manifestation.
Is that actually accurate, and what exactly sets them apart?
